In a previous paper, a simple model for failure and wear of unidirectional fiber-reinforced polymer composites was proposed. The model relates fiber stresses and sliding contact conditions to bulk wear rates for fiber orientation parallel to the sliding direction. In this work, the model has been extended to examine the case where the fibers are oriented transverse to the sliding direction, while still parallel to the plane of contact. When simulating the counterface contact with an ideal hemispherical asperity, the model overpredicts wear rates for the transverse fiber orientation. However, when the counter-face contact is simulated according to observed composite material transfer and corresponding surface topographical changes, indicating deviation from an ideal hemispherical asperity to a more general elongated or ellipsoidal form, the model correlation compares more favorably with existing friction and wear test data in the literature.Presented at the 50th Annual Meeting in Chicago, Illinois May 14–19, 1995
