Abstract

Disclosed is a friction-reducing and anti-wear composite material for a wading kinematic pair and a method of preparing the same. The friction-reducing and anti-wear composite material is prepared from carbon fiber (CF) among inorganic fillers, polyimide (PI) and polyether ether ketone (PEEK). These three materials are wet-mixed, dried and placed in a mold followed by curing by a heat press. The cured product is cooled and demolded to obtain the CF/PI/PEEK friction-reducing and anti-wear composite material for a wading kinematic pair. Tribological properties of the PEEK material are enhanced due to synergistic effect arising from hybrid organic-inorganic filling. The friction-reducing and anti-wear composite material provided in the invention has significantly reduced friction coefficient and wear volume loss under the seawater environment.
