【Abstract】 The effect of carbon fiber length distribution in the composite on its mechanical properties by optimizing screw assemble is studied and the wear behaviors are tested on a MM200 wear machine. The results show that optimum screw assemble can increase the mechanical properties of carbon fibers reinforced composite materials obviously. Optimum screw assemble can increase the proportion of long fibers in the resin, improve the reinforced effect; increase the wear resistance of CFRPA and lower the rub coefficient.更多还原
