Human body implant of graphitic carbon fiber reinforced ultra- high molecular weight polyethylene

摘要

A medical body implant element that is intended to experience rolling or sliding pressure during its function in the human body comprises microparticles of ultra-high molecular weight polyethylene which are fused together into a matrix. A quantity of graphitic carbon fibers of short, random lengths is disposed in intersticies of the matrix. The resultant composite is wear-resistant and substantially isotropic.
