摘要: Disclosed is an improvement in a femoral implant for a hip prosthesis involving a longitudinal shaft having a neck extending therefrom at an acute angle .theta. to the longitudinal direction made of layers of carbon fiber in a polymeric matrix, each layer containing unidirectional fibers and the layers arranged such that carbon fibers are oriented in the longitudinal direction and the .+-..theta. direction. The improvement involves balancing at least 50% of the layers in the .+-..theta. direction.
