Abstract
A bone replacement, for example a portion of a hip joint, a bone junction plate, or the like, includes a core element of a fiber-reinforced thermosetting material with a surface element made of a biologically compatible material, typically polyethylene, completely surrounding the core element. The outside surface element is internally interlocked with the core element, by being molded in one heat treatment operation which simultaneously cures the thermosetting material while molding the outside biologically compatible surface element thereto and interlocking and integrating the two elements into one unitary structure. Preferably, the fiber reinforcement is formed as fibers, woven mats, felted mats, or the like, and the surface element may, likewise, include a reinforcement beneath the surface actually in contact with the human body.
