Abstract : Continuous-fiber, woven E -glass composite femoral shells having the same elastic properties as bone were fabricated. The shells were then encrusted with filled-epoxy, wear resistant coatings and run dry against ultrahigh-molecular -weight polyethylene acetabular cups in 42 000- and 250 000-cycle wear tests on a total hip simulator. The tribological characteristics of these continuous4iber, particulate composite femoral shells articulating with ultrahigh molecular weight polyethylene acetabular cups were comparable to those of a vitallium ball articulating with an ultrahigh molecular weight polyethylene acetabular cup.
