Introduction Bone, which is a natural composite material, consists mainly of collagen fibers and an inorganic bone mineral matrix in the form of small crystal called apatite. Collagen is the main fibrous protein, the composite of mineral component in the body. Cartiligen is a collagen based tissue which contains large protein saccharit molecules that form a gel in which collagen fibrous are bonded. Bone replacement materials are required for variety of reasons. They may require when section of bone is missing and the gap needs to be filled. There are several options for the types of bone replacement. 1) Allograft: means material from another patient. 2) Auto graft: It means using material of a person from different site. The following polymer composite bio- materials are used for various bio medical applications: 1) Total knee replacement: polyethylene, carbon fibers and ultra molecular weight polyethylene. 2) Total hip replacement: carbon fibers-Epoxy carbon fiber- Polysulphone, polyeyhylene carbon fibers etc.…show more content…
Polymers make ideal matrix material, they can be processed i.e. fabricated more easily, with light weight and offer desirable mechanical properties. The reasons for the selection of these composites are low cost, high strength and simple manufacturing principles. The some of the commonly used areas of these biomaterials are joint replacements, total hip replacements, bone plate and bone cement, dental implants for tooth fixation, heart valves, contact lenses, vascular grafts, dialysis membrane, catheters, pace makers, leads, blood vessel prosthesis and opthalmagic
