  • Reinforced polyethylene for articular surfaces
    Patent number: 5609638
    Abstract: An articular component has a fibrous structure wherein the fibers are oriented normal to the articular surface. Wear debris reduction is attributed to the increased strength of fibers over bulk material and to the abrasion resistance associated with abrading a fiber bundle on the fiber tips. This is similar to the abrasion resistance seen in a household broom which is subjected to abrasion across the tips of the broom bristles. Reduced cold flow is attributed to the increased strength and stiffness of fibers over bulk material.
