As for this reason a natural composite is been introduce and one of it is using kenaf fibre. For this report, the natural composite is built from kenaf powder instead of fibre, bonded with epoxy or polyester and laminated with thin aluminium It is called kenaf powder composite laminate (KPCL). This study begins with the fabrication process of the composite for the KPCL using 20%wt of kenaf powder. The ke-naf powder been used in this study is from MARDI and with the size of 90u - 180u. The kenaf powder is not been heat treated and be used readily. The KPC is been fabricated in room temperature and been pressed under a weight of 300 kN and left to cure about 24 hours. Tensile test is been conducted to determine the mechanical properties such as maximum tensile stress and modulus of elasticity and the result indicate that the KPCL/epoxy has the highest value of maximum tensile stress that is 31.53 MPa and 6.64 GPa for modulus of elasticity. It is 58% higher than kenaf powder composite (KPQ/epoxy, 43% higher than epoxy, 26% higher than KPCL /polyester and 55% higher than polyester. In the fracture toughness test, the KPCL /epoxy gives the highest value that is 4.092 MPaVmthat is 17% higher than KPCL /polyester, 66% higher than KPC/epoxy, 70% higher than KPC /polyester, 0.6% higher than epoxy and 21% higher than polyester.
