In the USA, in-flight smoke events happened once a day [1]. Kenaf fiber is usually reinforced with synthetic based polymer resin such as polypropylene. The peak of tan is the determination of [48]. Introduction A fire ignition test was carried out in the laboratory by Izran et al. Researchers have noticed that some of the conventional products do not currently fulfill these requirements. MAPP creates an adhesive bridge for a better interface between fibres and matrixes [46]. The results showed that increases by adding kenaf content at all temperatures. To select a polymer, the Limiting Oxygen Index (LOI) is the prime consideration. These values are due to better ductility after the immersion process, caused by restricting the movement of polymer molecules [49, 50]. Yet they have some probability of becoming uncontrolled fires. Kenaf fibre is the most well-known natural fibre option studied by researchers. Besides this, DSC analysis concluded that adding a coupling agent will have no effect on both glass transition temperature, , and melting temperature, . Chaturvedi et al. Zainudin and K. Abdan2 1 Faculty of Engineering, Department of Mech. Review of kenaf fiber reinforced polymer composites. It can be categorized into four groups (as in Table 1) according to BS476: part 7: 1971. Part 1—fibres as reinforcements,”. [6] Han, J.S. This is a surface modification to link between the particles [44]. Therefore, the escaping timing can be extended to more than an hour. [33]. This paper reviews the published and ongoing research work on kenaf/synthetic and Kevlar®/cellulosic fiber-reinforced composite materials. Elongation at break properties of pure PLA, PLA/unbleached kenaf fiber composites (UBC) and PLA/bleached kenaf fiber composites (BC) are shown in Figure 6. 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 DMA program observed the time-dependent deformation behavior under periodic with very small amplitude . [2] have shown that more than 41% of fatalities are caused by fire and smoke in an aircraft crash. When the aircraft is old, some of the black sticky debris adheres to the wires, which is flammable. Review articles are excluded from this waiver policy. J. E. McIntyre, The Chemistry of Fibres, 6, Edward Arnold, 2009. However, the degradation temperature of the polymer is much higher than natural fibres, for example, LDPE reinforced with kenaf fibre in the experiment. The DAP pretreatment on the fibre has dramatically lowered the temperature of the first thermodegradation moment, but it remains double/triple of char obtained at 500°C (Table 4). have determined that nitrogen application at 90 kgN/ha has significant effect for plant growing. Besides this, each fire analysis can detect different kinds of fire properties. As a result, MAPP modifications are able to reduce the LOI values more compared to SCA. Everything in the fire will eventually become charcoal, gases, and heat. Optimum fiber content 20%. From the results (Table 3), glass transition temperature, , and melting temperature, , were not influenced by the appearance of the silane coupling agent. 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 … BP shows good fire retardant behaviour and this agreed with the research carried out by Abdul Rashid and Chew [56]. We are committed to sharing findings related to COVID-19 as quickly as possible. Unfortunately, APP is not a good thermal stability agent. Sapuan, Z. Leman, M.R. The author discovered that Zb is a good FR, but Mg(OH)2 is even better at lowering the burning rate. For kenaf fibre there is long lists of research projects which have been done regarding its behaviour, and properties and modification made to it. The combination of natural fibers with synthetic fibers in hybrid composites has become increasingly applied in several different fields of technology and engineering. 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. Low visibility caused by two days of continuous rain and the surrounding by hills made rescue work harder. 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. Eliminating the ignition of a fire is the first priority, but the least we can do is to extend its ignition time. On the other hand, Suharty et al. strengths of the natural fiber reinforced polymer composites increase with fiber content, up to a maximum or optimum value, the value will then drop. Most of the natural fibres were implemented in daily life in Egypt from about 7,000 years ago [11]. 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. Lee et al. Fire causes substances to rupture. Rep. Doc 185, Society of Automotive Engineers, Washington, DC, USA, 2000. estructure Thus, the flammability of a natural fibre PMC requires much research from many aspects, and kenaf fibre can be said to be one of the most highly recommended natural fibres in the world. 423 fatalities are accounted for 18 major in-flight fire accidents from 1990 to 2010 [4]. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Kenaf fiber reinforced composites: A review. Kenaf is grown commercially in South East Asia country and widely used in the construction and infrastructure as well as in the automotive industry. Kenaf fiber is unique and potentially reliable. The percentage of fibre content is directly proportional to its value until 70 wt% of fibre. A. M. Mazuki, S. Safiee, Z. As the world’s technologies become more advanced, scientists are designing their inventions based on eco-environmental aspects. As a conclusion, neither acidic nor alkaline conditions make composites work better than in normal conditions. Energy Absorption of Natural Fibre Reinforced Thermoset Polymer Composites Materials for Automotive Crashworthiness: A Review Mohamed Alkateb, S.M. A. M. Mazuki, H. M. Akil, S. Safiee, Z. Abaca fibre as reinforcement in polymer matrices became popular due to applications of its polymer composite in production of exterior components of passenger cars. In-flight fires are normally detected at the beginning of the fire and can be successfully extinguished. Natural fibres were introduced and increasingly used due to their availability and environmental issues. 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). Postcrash fires are the most severe cases. Nanocomposite is the new area able to create high flame retardancy while withstanding a high load [32]. Kenaf fiber composite have a bright future due to its renewability and eco-friendly. 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 papers made are stronger, whiter, of higher duration for yellowing resistance, and smoother for printing [14–16]. Nevertheless, these treatments do enhance its tensile strength, young’s modulus, and elongation ability. When small sparks land on this aging wiring, fast and uncontrollable fire occurs. A Review on Applications of Kenaf Fibre Reinforced Composites Author : Sasikumar Gnanasekaran and Sivasangari Ayyappan Volume 7 No.2 July-December 2018 pp 110-112 Abstract. When the fire is somehow ignited, work has to be done to reduce the fire propagation rate. Maintenance is very important to ensure a safe environment on an aircraft. The first peak of mass drop for kenaf fibre is hemicelluloses degradation and this begins at around 200°C [34]. The following preliminary research has investigated the use of Kenaf, Hibiscus cannabinus, as a possible glass replacement in fiber reinforced composites. Natural fibre has fast growing and abundance properties which make it available at very low cost. This review paper deals with the previous and current works published on the kenaf fiber composites. Keywords: Polymer composite, kenaf fiber, SEM 1. It has the lowest 5% weight lost temperature and char residue. 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. & Manufacturing Engineering, University Putra Malaysia 2 Laboratory of Biocomposite Technology, Institute of Tropical Forestry and Forest Products Universiti Putra Malaysia, Malaysia The most potential fire source is electrical. By having TGA, it was found that the fire behaviour of composites tends towards fibre fire behavior when its proportion increases in composites. Mazuki, S. Safiee, Z.A.M. Natural fibers are getting attention from researchers and academician to utilize in polymer composites due to their ecofriendly nature and sustainability. 2. Kenaf fiber has been widely used as reinforcement in composites over the past few years which is a most attractive alternative due to its rapid growth at different climatic conditions and ensuring low cost; kenaf fiber has gained some attention to replacing the glass fiber … In 2010, a tragic postcrash fire occurred and 158 passengers died. Besides this, there are increases of when the kenaf content is getting higher. 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.
