Abstract

Abstract: Composites have been found to be the most promising and discerning material available in everywhere in the world. The important requirement of biomaterial to be used as orthopaedic implant is their resistance to wear against the interacting part. In the present investigation, polymer matrix composites are produced from collagen fiber and epoxy matrix with varying volume fraction of fibers namely 10%, 20%, 30% and 40%. Test specimens prepared from the produced composite and subjected to pin on disc wear test to determine the wear rate for the collagen fiber reinforced polymer matrix composites to find the material's use as a bio-implant. The wear test was performed using a normal load of 5 to 20 N, a manually selected track diameter, and a fixture that can take discs up to 165 mm in diameter and 8 mm thick. Here, their usage in orthopaedics as an implantable material in bone surgery was considered and studied. Bone fixation plates, hip joint replacement, bone cement, and bone transplant are just a few of the applications for these composite materials in orthopaedics.
