摘要：

An experimental study of Ultra-High Molecular Weight Polyethylene (UHMWPE) and hydroxyapatite (HAP) nanocomposites for the purpose of joint prosthesis is investigated under quasi-static and dynamic loading conditions. By employing compression mold process, five different volume fractions of hydroxyapatite nanoparticle reinforced nanocomposites are made. Quasi-static tension and compression tests are performed using ASTM test methods. Dynamic compression characterization is performed using split Hopkinson pressure bar technique. The nanocomposite performance as a function of volume fraction under a typical loading rate is investigated. The results of the fabricated nanocomposites are compared with currently employed UHMWPE in the joint implants. For comparison purposes, separate sets of tests are performed on currently employed UHMWPE. This comparison provides a valid measure to identify the optimum volume fraction of hydroxyapatite that can be used without compromising the integrity of the UHMPWPE in joint prosthesis.
