To explore the friction and wear properties of carbon fiber-reinforced polyetheretherketone(C-PEEK)composite specimens under different operating conditions,high-precision C-PEEK composite specimens were fabricated using fused deposition modeling(FDM)3D printing.The specimens were then subjected to reciprocating friction and wear tests using a pin-on-disc tribometer under various pairing counterparts,external loads,sliding velocities,contact durations,and temperature conditions.The results showed that,although the wear volume of C-PEEK material increased with increasing contact duration,sliding velocity,and external load,the friction coefficient remained generally below 0.3,indicating good wear resistance.Under the conditions of a sliding velocity of 15 mm/s,a load of 30 MPa,and a test duration of 1 h,the wear volume of C-PEEK material increased with temperature elevation,while the friction coefficient gradually decreased.Additionally,at a temperature of 200℃,the friction coefficient between GCr15 steel ball and C-PEEK friction pair could be as low as 0.15,demonstrating the excellent friction and wear properties of C-PEEK composite material.
