The effect of kenaf fibre content and the silane treatment of PP/NBRv/kenaf composites were studied and fabricated via melt mixing at 180 ˚C for 9 min using 15 rpm motor speed. By using silane as a coupling agent for PP/NBRv/kenaf fibre composite, the mechanical and morphological properties have been improved compared to PP/NBRv/kenaf fibre composite without silane treatment. The composites were examined by using Universal Testing Machine (UTM) for tensile testing and Scanning Electron Microspcope (SEM) for morphological study. The tensile strentgh of PP/NBRv/kenaf with and without silane treatment decreased with increasing amount of kenaf filler content but increased in the Young’s Modulus. However, composites with silane treatment indicated better strength values than the composites without silane treatment. The morphology observations of composites have supported the tensile properties which indicated better interaction between the filler and matrix for treated composites.
