Mechanical and Tribological Properties of Fiber Reinforced Ekonol Composites

Abstract

Carbon fiber(CF) and Kevlar fiber(KF) were used as reinforcing agents to fill Ekonol(EK) respectively. Mechanical and tribological properties of composite systems were tested. When CF was used as the EK reinforced filler, the mechanical properties of EK composites couldn’t be enhanced obviously, and the tribological properties were reduced. When KF was filled in EK matrix, it could greatly improve the impact strength of EK composite by reducing crack formation and inhibiting crack propagation. The KF/EK composite has good tribological properties. It keeps the high friction low wear performance advantage of EK, and solves its problem of forming difficulty. In EK composite, KF plays the role of reinforcing agents and friction modifier at the same time, and then it is a kind of excellent EK reinforced filler.
