Abstract
A "ready-made" stem in a hip replacement arthroplasty might not suite to individual's femur. The adoptable stems will help patients recover in short period and completeness. Fiber Reinforced Plastic (FRP) can give various mechanical properties because of its abundant design parameter. For example, choice of reinforcement fiber and matrix resin, control of fiber volume fraction, fiber orientation, and structure of laminates stacking. FRP enables the adaptive design of various mechanical properties, therefore, the design is complex in nature. Furthermore, by combining a numerical analysis with these properties of FRP, minimally invasive design of the stem is possible. A "tailor-made" composite stem, which supports steady recovery and provides high reliability, would be applicable by using FRP. In this paper, the design procedure of stems with FRP has been described.
