The major investigation of this work is to replace the synthetic fiber polymer composite helmet to natural fiber reinforced polymer helmet. This study examines the mechanical properties such as impact strength, impact modulus, flexural strength, hardness and water absorption capacity. It is performed to develop the natural fiber hybrid composite helmet. The fiber reinforcements are short neem fiber and alkali treated banyan woven fabric is used. The weight percentage of laminates contain as matrix 85% (510g) and reinforcement 15% (90g), the matrix consists of epoxy resin (450g), hardner (45g) and the granite powder is used as a filler material (15g), which is fixed for all samples and varied in the fiber weight ratio of Neem/Banyan (grams), natural fibers are 15/75, 30/60, 45/45, 60/30, 75/15. The result shows the weight fraction of neem fiber 12.5% (75g) and banyan 2.5% (15g) gives high impact strength and it can be applied for fabricating the motorcycle driving helmet.
