Design of Artificial Hip Joint by Carbon/PEEK Composites

Abstract:

The purpose of this study is to determine the correct estimation of the various designs for artificial hip joint of the Carbon/PEEK composites. Validity of the study has been tested with the alternative materials for the metal-based materials for artificial hip joint. Moreover, this work evaluated the FEA according to the fiber ply orientation and the condition of load. The stem shape of two kinds was designed through the normal shape of the femur. Three load cases of 1kN, 2.5kN and 5kN were used for each of FEA model. In the case of general shape, the results by ply configuration showed that the stress of ply configuration I was lower compared to ply configuration II and III. On the other hand, in the case of curved shape, ply configuration II were lower compared to ply configuration I and III. The result was checked that the stress of curved shape was higher than that of the general shape in the load of 2.5kN. It could be confirmed then that a similar phenomenon would occur in the condition of 5kN load. However, in the case of ply configuration II, the stress of the curved shape was lower than the stress of the general shape.
