The development eagerness toward the composites field gives significance, especially foreco- friendly materials and products. Hence, this research is to investigate the mechanical properties and to obtain the optimum tensile strength properties of silica (rice husk ash) and kenaf fibre reinforce polypropylene(pp). This study has two different grades of rice husk silica (79.09 % wt and 95 % wt). Tensile strength from the proportion of 30% kenaf – 70% PP and 40% kenaf - 60% PP with the different percentage of RHA which is 0%, 2%, 6% and 10% have been recorded. PP - kenaf - RHA were mixed and been through injection moulded for further study about their tensile strengths. Overall 30% wtkenaf and 70% wt PP shows the best result of tensile strength at 2% RHA while for 40% wtkenaf and 60% wt PP has best result tensile strength at 10% RHA.
