With chopped carbon fiber(CF) as filler,long and short CF/polyetheretherketone (CF/PEEK) composite materials were prepared by injection molding method.The surface wettability of the materials was Explored by measuring the water contact angle.The tribological properties were studied through friction and wear experiments.The results shown that after adding CF,the surface contact angle of the materials increased,and the longer the fiber,the larger the contact angle.The friction coefficient and friction amount of CF/PEEK were lower than pure PEEK,and the friction coefficient and wear amount of long fiber CF/PEEK were lower than that of short fiber CF/PEEK.It shown that CF can play the role of anti-friction and lubrication,so that the friction coefficient of CF/PEEK was reduced.The length of CF will also affect the tribological performance.Long fiber materials had better friction resistance performance.
