In order to find a convenient method for preparing nano-SiC reinforced carbon fiber laminates， the nano-SiC particles were uniformly dispersed in anhydrous ethanol to prepare nano-SiC reagent with different mass fractions， and then the nano-SiC reagent was uniformly sprayed on the surface of carbon fiber prepregs and solidified. The friction and wear tests of different specimens were carried out to obtain the effects of different content on the friction coefficient and wear amount of carbon fiber laminates， and the wear morphology and hardness of composites were analyzed. The experimental results show that spraying nano-SiC particles on the surface of carbon fiber prepreg can effectively improve the friction and wear performance of carbon fiber laminates. When the concentration of nano-SiC is 1%， the friction coefficient， wear， width and depth of the laminates decrease by 52%， 63%， 32.3% and 54.8%， respectively， compared with that of the specimens without nano-SiC.
