Abstract: Oil-impregnated polydicyclopentadiene (PDCPD) are prepared by a simulating reaction injection molding (RIM) system. The tribological properties of the composite under high sliding speed (5~20 m/s) are evaluated on a MMS-1G friction and wear tester. The results show that the incorporation of oil in PDCPD contributes to reduction on both wear rate and friction coefficient. The sliding speed has no significant influence on wear resistance of neat PDCPD while the tribological behavior of oil-impregnated PDCPD is sensitive to sliding speed. Under lower sliding speed, neat PDCPD is characterized by abrasive wear,under higher sliding speed, adhesive wear and micro-pit damage are dominated. The wear mode of oil-impregnated PDCPD is mild surface scratch and fatigue wear and completely different from that of the neat PDCPD.

Key words: PDCPD; friction under high velocity; tribological property
