Carbon fiber reinforced plastic (CFRP) is light-weight and is used for the body of the rocket and the jet, the F1 car from high strength. The manufacture of CFRP had a problem with high cost because it hardened a heat harden-ability resin with the hot and high-pressure autoclave. The authors used the silicon rubber which distributed ceramic particle for the cost reduction as the forming type and applied CFRP to the leg of model car chassis and CCD camera built-in 2 leg walking robot by the press forming. The high-precision of the CFRP product, 0.5% of size precision, was done. Also, the plastic which distributed Al_2O_3 particle showed equal to or more than 3 times of wear resistance of steel. Therefore, it used clay as the molding die material, 7 times of wear resistance were shown to alloy of aluminum of the place to have made a bicycle pedal from CFRP which distributed Al_2O_3 and it achieved 57% of lightening to aluminum alloy.
