In the past decades, the extensive studies had been accomplished on the natural fibre reinforced polymer composites (NFPC) and are still continuous until today. The composites made of natural fibre and polymer has proven the better effectiveness in high impact fatigue strength and toughness. The increases of fibre loading give higher results fundamental in strength due to its high interfacial bonding between the fibre. In the present work, experimental tests were carried out to study the mechanical properties; tensile, hardness and impact and morphological characterization: Scanning Electron Microscope (SEM) of the NFPC. The composites fabricated are between the Kenaf fibre and epoxy resin. The Kenaf fibre reinforced epoxy resin composites were fabricated using hand layup technique by layering the arranged fibre with polymer in the mould with different angle orientation (22.5° and 67.5°) as the main parameter observed and the fibre composition (2%, 4% and 6%). Before the fabrication started, the fibre had undergone the alkali treatment for the effective surface modification that can enhance the interfacial bonding between the fibre. [ABSTRACT FROM AUTHOR]

Natural fibre composition is one of the excellent alternative for the most extensively utilized fibre in the composite revolution such as covers; vehicle door’s panel and automobile roofs. Renewable, low cost and also decomposable (biodegradable) are some of benefits natural fibre composites. In latest years, a lot of researchers involved in natural fibre project to reinforced polymer. This study was done using kenaf fibres and polyurethane (PU) as the polymer. Composites have been organized the usage of the three unique percentages of composites 2%, 4% and 6% of kenaf fibre. The hardened composites were cured for 24 hours earlier than it was once shaped in accordance to precise dimensions. Mechanical tests were performed on the samples to study the behavior. In addition, the morphology of the materials were observed using scanning electron microscope (SEM) Result found that the 6% of kenaf fibre has the highest hardness value, tensile as well as impact strength. It could be seen using SEM that 6% fiber loading showed lesser void and superior interfacial bonding between the fiber and polymer matrix. [ABSTRACT FROM AUTHOR]
