Abstract

As biomedical engineering continues to advance in the modern age, basic engineering materials have become more useful despite their other engineering applications. Total Hip Replacement (THR) has remained as one of the biggest achievements in the history of biomedicine. As the demand for hip implants continue to increase, the necessity to improve the quality of these implants continues to increase every day. The following project provides a detailed understanding of the highlighted materials and techniques that have contribute to the development and failure of hip implants. The purpose of this project to provide a failure analysis of the hip implants currently being used in the industry and perhaps provide an alternative material as a feasible option to increase the quality of the implants.

The use of carbon fibre reinforced composite materials for biomedical hip implants is primarily focused in the following project to propose a theoretically justified preliminary design. The design is validated through a detailed Finite Element Analysis and Abrasive testing using standard methods. The results obtained through FEA suggested the addition of CFR-PEEK layer for femoral head surface offers the desirable strength and durability. To further validate the model, the abrasive test results demonstrated relatively low wear rates compared to most of the material specimens used.
