Increasing the thickness of the wire insulation does help to prevent short-circuiting of the wires. Hybrid composites of wood flour/kenaf fiber and polypropylene were prepared at a fixed fiber to plastic ratio of 40 : 60 and variable ratios of the two reinforcements namely 40 … Davoodi et al. The core shows an isotropic and almost amorphous pattern, while the bark has an oriented high crystalline fibre pattern [22]. It is not discussed in this review due to its newness which means there is a lack of research information on the natural fibre reinforced in nanocomposites. Researchers Kuchinda et al. A fire ignition test was carried out in the laboratory by Izran et al. 2. Optimum fiber content 20%. Kenaf fiber is unique and potentially reliable. The kenaf bast fiber is known to have the potential as a reinforcing fiber in When the aircraft is old, some of the black sticky debris adheres to the wires, which is flammable. Natural fibre composites are subject to thermal decomposition when exposeding to fire or high-intensity heat sources.

Limiting oxygen index (LOI) and heat release rate (HRR) of some polymers [, Thermal behavior of kenaf/PLA composites [, A Review of the Flammability Factors of Kenaf and Allied Fibre Reinforced Polymer Composites, Department of Mechanical and Manufacturing Engineering, Universiti Putra Malaysia (UPM), 43400 Serdang, Selangor, Malaysia, Advances in Materials Science and Engineering, http://www.guardian.co.uk/world/2010/may/22/india-budget-airline-jet-deaths, http://www.boeing.com/commerial/aeromagazine/aero_14/inflight_story.html, http://www.sensata.com/download/AgingAircraftConf-Sept2003.pdf, DAP-treated coconut filter fibre 2.5%/PLA, (i) An swelling material, char formers and stop the fire propagation, (i) Acts in the condensed phase to direct chemical reactions inside burning. This phenomenon leads to a reduction of the product’s strength. Therefore, this paper presents an overview of the developments made in the area of kenaf fiber reinforced composites, in terms of their market, manufacturing methods, and overall properties. Magnesium hydroxide [Mg(OH)2] is the popular metal hydroxide FR for polymers due to its high endothermic nature and water yield behavior. Besides this, the authors realised that the amount of kenaf content does affect the value of the experiment. Thermal instability is a drawback of natural fibre polymer composites. For kenaf fibre there is long lists of research projects which have been done regarding its behaviour, and properties and modification made to it. Expelling the wastewater containing dye compounds into clean water will dissolve the oxygen content in the water and prohibit sunrays passing through the water as well. Therefore understanding the flammability of natural fibre based polymer composites could modify its fire behaviour thus allowing passengers more time to escape from an incident. However, it adds weight to the aircraft. The increase of crystalline caused by the kenaf fibre was stimulated into heterogeneous crystallization. MAPP creates an adhesive bridge for a better interface between fibres and matrixes [46]. A. M. Mazuki, H. M. Akil, S. Safiee, Z. Omar, A.A.M. The ordinary polymer matrixes are thermo-set, thermoplastic or biopolymer. Long bast fibre types are used to make high- grade pulps for the pulp and paper industry, composite boards, or textiles. Besides this, different types of polymers with different characteristics will cause the composites to have different fire behavior. The composites were pretreated by a silane coupling agent (SCA) in the amount of 1–5%. [55]. Chen, “Elastic moduli and damage mechanisms in 3D braided composites incorporating pultruded rods,”, H.

ScienceDirect ® is a registered trademark of Elsevier B.V. Kenaf fiber reinforced composites: A review. One is that kenaf absorbs the nitrogen and phosphorus that are present in the soil. BP is able to extend its ignition period more than untreated board by doubling the time to 2 minutes. Besides this, the combustion of biocomposites produces fewer toxic gases compared to conventional composites. Review articles are excluded from this waiver policy. Aircraft cabin fires are generally grouped in ramp fires, in-flight fires, or postcrash fires. Ishak et al. The papers made are stronger, whiter, of higher duration for yellowing resistance, and smoother for printing [14–16]. Understanding its flammability factors and improving them will help to delay passenger panic and hence extend the escape time. These engineered fibres are being produced with uniform properties in every single fibre in terms of dimensions and mechanical properties [10]. Although APP has relatively poor thermal stability properties, Zhang et al. The peak of tan happened earlier and was reduced compared to the standard sample after the immersion process. As the world’s technologies become more advanced, scientists are designing their inventions based on eco-environmental aspects. This paper reviews the published and ongoing research work on kenaf/synthetic and Kevlar®/cellulosic fiber-reinforced composite materials. Fig. The most potential fire source is electrical. Meanwhile, the DSC could determine some important parameters, such as oxidation, glass transition temperature (), crystalline level, and melting temperature [31]. This may be due to the chemical altering reaction caused by the treatment component. Nanocomposite is the new area able to create high flame retardancy while withstanding a high load [32]. Besides, BP has the lowest of burnt area and the second least weight loss. estructure This is because the thermal behaviour of kenaf fibre takes priority as increasing its content. [6] Han, J.S. T. Potter, M. Lavado, and C. Pellon, “Methods for characterizing arc fault signatures in aerospace applications, Texas instruments,” 2013, P. J. Herrera-Franco and A. Valadez-González, “Mechanical properties of continuous natural fibre-reinforced polymer composites,”, H. M. Akil, M. F. Omar, A. The first cycle is below 100°C, while the second cycle is below 200°C. Kenaf fiber composite can be produced using conventional fiber composite manufacturing. Boeing Aero, “Flight and cabin crew response to in-flight smoke,” 2013. The ignition time widely depends on the heat intensity, the oxygen density, and the air flow in that particular area. Kenaf (Hibiscus Cannabinus L.) fibres are thermally and alkali treated to enhance the interfacial bond between the fibre-matrix, the mechanical properties of the fibre itself, the fibre-reinforced thermally activated alum sludge ash (AASA) and the nanosilica (NS) blended cementitious composites. In general, the elongation at break properties of the composites decreased when 10 wt% of kenaf fiber was added and the value was gradually reduced with more addition of kenaf fiber. Review of kenaf fiber reinforced polymer composites. [54] took the challenge to integrate it with a silica synergistic agent. analyzed the kenaf fiber reinforced poly-lactic acid for its mechanical properties. ► Kenaf fiber composite can be produced using conventional fiber composite manufacturing. 0 %, 5 %, 10 %, 20%, 30 % and 40 %. 423 fatalities are accounted for 18 major in-flight fire accidents from 1990 to 2010 [4]. Natural fibres namely sisal, jute, kenaf, hemp, abaca and banana are mainly used in … Last but not least, the particle size is the main factor which influences its efficiency, due to the large surface area of the fine particle. The aim of this review article is to provide a comprehensive review of the foremost appropriate as well as widely used natural fiber reinforced polymer composites (NFPCs) and their applications. The matrix of the composite will melt away, and the fibre is under thermal decomposition as well. Lignin decomposition is the last component in decomposition at the highest temperature. Numerous studies have been conducted on kenaf and its hybrid composites. Kenaf fiber is extracted from bast fiber of kenaf plants. Kenaf fiber is usually reinforced with synthetic based polymer resin such as polypropylene. This review paper deals with the previous and current works published on the kenaf fiber composites. As a conclusion of both papers, Mg(OH)2 gives the most thermal stability, Zb exhibits the most char residue, and APP reduces the burning rate the most. Demir et al. A. Bakar, “Degradation of dynamic mechanical properties of pultruded kenaf fiber reinforced composites after immersion in various solutions,”, X. Qu, A. Wirsén, and A.-C. Albertsson, “Effect of lactic/glycolic acid side chains on the thermal degradation kinetics of chitosan derivatives,”. [35] conducted an experiment regarding the effect of kenaf fibre content on composites when in a fire. Nevertheless, these treatments do enhance its tensile strength, young’s modulus, and elongation ability. It is built up of an outer layer of bark and a core. The study found that kenaf is a suitable candidate for reinforcement in biodegradable polymer composite. However, TGA testing tells us that surface treatment has decreased the carbonaceous residue to 18% and 15%, respectively for SCA and MAPP as compared to 24% residue for untreated composites. Zainudin and K. Abdan2 1 Faculty of Engineering, Department of Mech. Mazuki, S. Safiee, Z.A.M. The rate of fire propagation determines the flame classification of the materials that spread across the surface. The kenaf fiber polypropylene composites have a higher The most important criteria are the ignition time, rate of propagation, and fire behavior. As increases occurred in the portion of APP, some big cell sizes formed irregular shape and this disturbed the original formation of wood/PP particles. Components like polymers and natural fibres are natural fire conductors. This TG result is shown in Table 6 and it did improve the char residue portion. morphological analysis of kenaf fiber reinforced polymer composites has been discussed. Only eight passengers have saved themselves in this incident. In addition, it presents summary of various surface treatments applied to natural fibers and their effect on NFPCs properties. J. Shaw, “A review of smoke and potential in-flight fire events in 1999,” Tech. To estimate its flammability, a wide range of factors can be considered such as fibre content, type of matrices, pH conditions, treatment, and fire retardant (FR) filler’s type. In the USA, in-flight smoke events happened once a day [1]. The authors found that the value from the DMA testing is getting lower when the temperature is rising. The values were reduced to 4 GPa, 3.8 GPa, and 3 GPa for pH 7, pH 5.5, and pH 8.9 separately at their (172°C). Heat emerges as a result of the chemical reactions of the combustion process. ► Kenaf fiber composite have a bright future due to its renewability and eco-friendly. Despite this, lumens of natural fibre are excellent acoustic proofing for particleboard [19, 20]. These composites bring us about high mechanical and thermal properties which are the main characteristic required in various applications from aerospace to sport uses. These minerals also help to increase cumulative weed weight, crop height, stem diameter, and fibre yield [25]. The decreased from 172°C to 162°C, 155°C and 150°C for neutral, acidic and alkaline solution, respectively. Heavy-bromine gases cover the material from touching oxygen and heat, The compounds alone do not work much, yet are powerful in combination with halogens forming antimony trihalide to scavenge free radicals and increase char formation, (i) An inorganic compound thus healthy and environmentally safe, (i) Recognised as inert diluent and shows some flame retardant effect, Function primarily by a vapour phase flame inhibiting mechanism through radical reaction, Flame retardant portion in wood/PP Sample. Review Kenaf fiber reinforced composites: A review H.M. Akil⇑, M.F. Natural fibers are getting attention from researchers and academician to utilize in polymer composites due to their ecofriendly nature and sustainability. From the results (Table 3), glass transition temperature, , and melting temperature, , were not influenced by the appearance of the silane coupling agent. BP shows good fire retardant behaviour and this agreed with the research carried out by Abdul Rashid and Chew [56]. The properties of NFPCs var… Energy Absorption of Natural Fibre Reinforced Thermoset Polymer Composites Materials for Automotive Crashworthiness: A Review Mohamed Alkateb, S.M. The bark contributes 30–40% of the dry weight for the stem and shows a dense structure. The following preliminary research has investigated the use of Kenaf, Hibiscus cannabinus, as a possible glass replacement in fiber reinforced composites. The authors declare that there is no conflict of interests regarding the publication of this paper. It is believed that more studies will focus on this area in the future. Therefore conventional engineering fibres such as glass and carbon fibres, gradually substituted by natural fibre and sometimes use along with mineral fillers to meet the specification of certain task [9]. TheGuardianNews, “India Jet Crash Leaves More Than 150 Dead in Mangalore,” 2013. A. M. Mazuki, S. Safiee, Z. At the same time, storage modulus, , and loss of modulus, , are increasing as well through DMA. Nevertheless, Jeencham et al. Zampaloni et al. Therefore, composites made up from natural fibre as reinforcement, combined with biodegradable polymer matrices, are the best solution for the environmental issues yet still retain the required strength and properties. The high moisture adsorption of the natural fibre allowed the absorption of the pigment in the waste water [17]. A survivor, who described the incident, said he heard a loud bang and the plane caught fire. 2014, Article ID 514036, 8 pages, 2014. https://doi.org/10.1155/2014/514036, 1Department of Mechanical and Manufacturing Engineering, Universiti Putra Malaysia (UPM), 43400 Serdang, Selangor, Malaysia. The rate of fire spread is tested by fire propagation test [27]. The photosynthesis rate of kenaf is much higher than the photosynthesis rate of conventional trees [21]. The composites were prepared from nonwoven kenaf and polypropylene (PP) by varying the fibre content from 0% to 40%. Most of the natural fibres were implemented in daily life in Egypt from about 7,000 years ago [11]. strengths of the natural fiber reinforced polymer composites increase with fiber content, up to a maximum or optimum value, the value will then drop. Three samples with 70% of kenaf fibre content were immersed in pH 5.5, pH 7, and pH 8.9, which represent acidic, neutral, and alkaline solutions, respectively, for 24 hours. Mianowski, T. Lin, Y. Validity of Plant Fiber Length Measurement: A Review of Fiber Length Measurement Based on Kenaf as a Model In Kenaf Properties, Processing and … Natural fibres were introduced and increasingly used due to their availability and environmental issues. Chaturvedi et al. Besides this, there are increases of when the kenaf content is getting higher. The first peak of thermal degradation for 20% kenaf fibre loading is 246°C and this shifted to around 217°C for 50% fibre content. Natural fibre has fast growing and abundance properties which make it available at very low cost. [33]. [16] used kenaf fiber neutral polypropylene reinforced composites. In-flight fires are normally detected at the beginning of the fire and can be successfully extinguished. The survivor escaped by jumping out of the opening where the plane had cracked. A. Rashid, F. Abood, and S. Rahim, “Optimising treatment system for kenaf (, A. M. Abdul Rashid and L. T. Chew, “Fire retardant treated chipboards,” in, United States Government General Accountability Office, “Aviations safety: status of FAA’s actions to oversee the safety of composite airplanes,”, P. Joseph and J. Ebdon, “Recent developments in flame-retarding thermoplastics and thermosets,” in. The results show that the storage modulus of the sample was decreased after the immersion process. The peak of tan is the determination of [48]. [47] have revealed TGA outcomes that are totally different. Flight Safety Foundation, Aviation Safety Network on 24th May 2013, E. R. Galea and N. C. Markatos, “A review of mathematical modelling of aircraft cabin fires,”. B. Kandola, “Nanocomposites, Fire Retardant Materials,” A. R. Horrocks, Ed., Woodhead Publishing, Cambridge, UK, 2000. An Air India Express Boeing 737-800 accidentally crashed when it landing in pre-monsoon rains and then plunged into the jungle [6]. Fortunately, they have a very low probability of becoming uncontrolled in-flight fires. When small sparks land on this aging wiring, fast and uncontrollable fire occurs. The results also showed that the optimum fiber Natural fibers, characterized by sustainability, have … This is because of the increase of stiffness of the composite. At the same time, increasing the kenaf quantity led to a drop of value. However, the degradation temperature of the polymer is much higher than natural fibres, for example, LDPE reinforced with kenaf fibre in the experiment. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. The main temperature peak for pure TPU is around 363°C and is caused by polymerization. C. H. Lee, Mohd Sapuan Salit, M. R. Hassan, "A Review of the Flammability Factors of Kenaf and Allied Fibre Reinforced Polymer Composites", Advances in Materials Science and Engineering, vol. To select a polymer, the Limiting Oxygen Index (LOI) is the prime consideration. LOI is the elementary density of oxygen in a percentage that supports the combustion of a polymer. Yet they have some probability of becoming uncontrolled fires. Energy absorption, fiber type, matrix type, fiber … In general, the implementation of FR filler into flammable materials such as natural-based polymer composites does increase the fire behavior of the sample. The photosynthesis rate of kenaf is 23.4 mg CO2/dm2/h as compared to conventional trees of 8.7 mg CO2/dm2/h under 1000 μmol/cm2/s [26]. [43] investigated the viscoelastic behavior for Kenaf/Polylactic Acid (PLA) composites with a DMA test. However, different environments will still yield various heights of kenaf plant, such as the cultivar, planting date, photosensitivity, length of growing season, plant populations, and plant maturity. The study shows that the flexural properties of Besides this, DSC analysis concluded that adding a coupling agent will have no effect on both glass transition temperature, , and melting temperature, . Chemical compounds are the most commonly used FR fillers. By having TGA, it was found that the fire behaviour of composites tends towards fibre fire behavior when its proportion increases in composites. By continuing you agree to the use of cookies. Yet the mechanical properties were nearly halved for all properties, such as compressive strength, wear ability, and tensile strength. They usually come in the form of a powder and contain 5 to 10% of it inside the sample. Fire causes substances to rupture. SCA will undergo hydrolysis and condensation reactions to form silanol groups. Natural fibre has fast growing and abundance properties which make it available at very low cost. Fire behaviour properties are significant factors for natural fibre based polymer composites in terms of safety. However, both of the heat of fusion () and the degree of crystalline () had increased about 4 J/g and 4%, respectively. Copyright © 2011 Elsevier Ltd. All rights reserved. Even humans in the Stone Age combined some short length fibres and twisted them together as cords and yarns [12]. thermogravimetric analysis (TGA), different scanning calorimetric (DSC), and dynamic mechanical analysis (DMA) are the three most famous methods used to investigate the fire behaviour of composites. DSC measurement is also being conducted in research. Higher flame resistances of particleboard made by flame retardant-treated kenaf fibre have been published compared to conventional particleboard [18]. Part 1—fibres as reinforcements,”. Two thirds of smoke event on Boeings from year 1992 until year 2000 were caused by electrical (64%) [7]. https://doi.org/10.1016/j.matdes.2011.04.008. The sample is made of kenaf core particles with 180°C hot press. Sapuan , E.S. Kim, and J. R.

A few types of fire retardant filler added into the sample tend to get better results, such as monoammonium phosphate (MAP), diammonium phosphate (DAP), and a mixture of boric acid, guanylurea phosphate, and phosphoric acid (BP). [2] have shown that more than 41% of fatalities are caused by fire and smoke in an aircraft crash. The combustibility or lowered flame retardancy hampered the diverse applications of kenaf fibers reinforced polymer composites, as it affects the mechanical strength and stiffness of composites during fire. There will start a fire from smoke or fume. A measurement of HRR for a PP matrix with four natural fibres reinforced combinations was conducted by Kozłowski and Władyka-Przybylak [41]. The author discovered that Zb is a good FR, but Mg(OH)2 is even better at lowering the burning rate. & Manufacturing Engineering, University Putra Malaysia 2 Laboratory of Biocomposite Technology, Institute of Tropical Forestry and Forest Products Universiti Putra Malaysia, Malaysia Kenaf Thermoset Composites Composites Tensile strength, Tensile MPa modulus, GPa Kenaf reinforced UP 20 - 90 4-7 40 -50 4-5 Kenaf reinforced VE Kenaf reinforced 50 - 65 3-5 Epoxy Elongation at break, % 0-2 0-3 1-3 Flexural strength, MPa 40 - 123 60 - 80 70 - 100 Flexural modulus, GPa 4 - 14 3-5 3-5. In 2010, a tragic postcrash fire occurred and 158 passengers died. However, these advantages come along with environmental issues. The highest growing rate may be up to 10 cm/day. Fire propagation capabilities depend on the total heat liberated and the fire spread for a fuel [27, 28]. Kenaf is grown commercially in South East Asia country and widely used in the construction and infrastructure as well as in the automotive industry. The results showed that increases by adding kenaf content at all temperatures. All results show that the kenaf natural fibre shifts the onset thermal degradation temperature a little bit to the left for all matrices with the same fibre content. Everything in the fire will eventually become charcoal, gases, and heat. Kenaf is the most common natural fiber used as reinforcement in polymer matrix composites (PMC). This means that the kenaf plant is environmentally friendly not only in terms of its biodegradability, but in the fact that it also produces a lot of oxygen as well as reducing carbon dioxide. Introduction Currently natural fiber composites have two issues that need to be addressed: resin compatibility and water absorption. As a substitute, there is an exponential growth of interest in using natural fibres. The stem of the kenaf is straight and there is no branching along the stem. Kenaf is also known as Hibiscus cannabinus L. It is an herbaceous annual plant that can be grown under a wide range of weather conditions and produces more than 3 m within 3 months even in moderate ambient conditions [21]. J. E. McIntyre, The Chemistry of Fibres, 6, Edward Arnold, 2009. The combination of natural fibers with synthetic fibers in hybrid composites has become increasingly applied in several different fields of technology and engineering. In the outcome, fibre contents were inversely proportional to the thermal stability. Therefore, easy separation of stem can be done either by chemicals or enzymatic retting. The candidates used in the research are completely biodegradable poly(3-hyroxybutyrate-co-3-ohydroxyvalerate) (PHBV), random copolyester of poly(butylenes adipate-co-terephthalate) (PBAT), and low-density polyethylene (LDPE). Table 5 shows some FR groups and their ways of functioning. POLIMERY. Although the presence of the natural fibre brought an earlier ignition, the heat released by natural fibre composites was noticeably reduced by more than 50% of the pure PP matrix. It has the lowest 5% weight lost temperature and char residue. One result which was the same as that of other researchers is that the fibre content increased the crystalline degree of the sample. In a modern aircraft, there is over 150 km of wire; any single point of wiring fault might cause an uncontrolled fire [8]. When the fire is somehow ignited, work has to be done to reduce the fire propagation rate. Among the many different types of natural resources, kenaf plants have been extensively exploited over the past few years. Kenaf fibre is the most well-known natural fibre option studied by researchers. As a conclusion, neither acidic nor alkaline conditions make composites work better than in normal conditions. Aji 1, S.M. Russo et al. The percentage of fibre content is directly proportional to its value until 70 wt% of fibre. Therefore manufacturers are keen to find lighter insulation materials. Therefore a third element (FR) is added into the recipe to increase the composite’s fire stability. After a while, the cabin was filled with smoke hence visibility and oxygen levels were very low. Conventional and traditional fibre reinforced composites can be made using carbon fibres or glass fibres inserted into unsaturated polyester or epoxy resins. The first thermal degradation will follow the degradation temperature of kenaf fibre at 350°C as loss of weight is the weight of the fibre content. However, the Young’s modulus of the natural fiber reinforced polymer composites increase with increasing fiber loading. The high quantity of kenaf fibre restricted the matrix amount. Therefore, a precise combination of natural fibre and polymer can enhance the thermal stability. The purpose of this review article is to clarify research and development in improving the mechanical properties of natural fiber reinforced polymer composites along with end applications. Lu, Z. X. Xin, C. K. Kang, and J. K. Kim, “Effect of flame retardants on mechanical properties, flammability and foamability of PP/wood-fiber composites,”, K. Izran, A. Zaidon, G. Beyer, A. [24] revealed that kenaf has been actively cultivated in recent years for two main reasons. Mazuki et al. These values are due to better ductility after the immersion process, caused by restricting the movement of polymer molecules [49, 50]. the specific properties are comparable. A. M. Ishak, and A. Table 7 lists the results of the test. A study focusing on kenaf fibre reinforced thermoplastic polyurethane (TPU) composites showed that the impact strength values of the materials prepared with the smallest size of kenaf fibre (<125 µm), medium size of kenaf fibre (125–300 µm) and the largest size of kenaf fibre (300–425 µm) were 2.1, 2.76 and 2.97 kJ/m 2, respectively . The other reason is that kenaf transforms carbon dioxide to oxygen at a significantly higher rate. a Corresponding author: fahmyjusoh@gmail.com NATURAL FIBER REINFORCED COMPOSITES: A REVIEW ON POTENTIAL FOR CORRUGATED CORE OF SANDWICH STRUCTURES A.F. For kenaf fibre there is long lists of research projects which have been done regarding its behaviour, and properties and modification made to it.
