A Novel Polymeric Composite for Orthopaedic Applications

摘要

The objective of this work is to develop a novel polymeric composite consisting of available materials that will be suitable for orthopaedic applications. Bovine Hydroxyapatite (HAp) has been reinforced with High Density Polyethylene (HDPE) and Carborundum (SiC) for improved mechanical properties. The X-ray diffractometer and microstructure of the HAp were examined. The results of the mechanical property tests revealed compressive strength of 40.9 MPa and elastic modulus of 697.5 MPa, with developed composite having HAp-35 wt%, SiC-32.5 wt%, and HDPE-32.5 wt% composition. The microstructural analyses of the various samples were examined as well. The developed biocomposite showed that it could serve as an alternative material for load bearing applications.
