This research uses natural fiber (hemp) and synthetic fiber (glass fiber). This bicycle helmet product was manufactured with used one layer of woven hemp fiber and one layer of random glass fiber and it is called hybrid composite. This helmet product uses vacuum infusion method. The product produced by this vacuum method has excellent porosity compared with handlay up and press mold method. The result of tensile strength test from radical fiber was 76,58 Mpa and modulus elasticity 12,71 GPa. Hybrid natural fiber composite is very feasible in the manufacture of bicycle helmet products because it exceeds the SNI standard of 38 Mpa. In the future this composite will be applied in the manufacture of motorcycle helmet products.
