Mechanical Properties of Silicone Rubber / Hydroxyapatite Composite

Abstract

Silicone rubber (SR) and hydroxyapatite (HA) are two well-known material that have been used as bone replacement. The flexibility and compatibility of SR and HA respectively, shows great performance and improvement in medical application. This paper investigate the mechanical properties of SR and HA composite with various phr loading of HA (0 - 30 phr). The results indicate that, HA loading phr of 25 phr and 30 phr were in the range of tensile strength of 5.76 MPa and 3.15 MPa respectively. Also, the hardness value of all the percentage loading of HA were above the hardness value of human vertebrae cancellous bone.
