Abstract
Epoxy resin was mixed with bone powder, PMMA and Animal hair at 0%, 0.01%, 0.05%, 0.1%, 0.5%, 1.5% and 5.0% levels. The tensile strength and the modulus were determined using Instron Universal Testing Machine. The results showed that as the filler load increases, modulus increases in the order: 848.472> 907.4847>939.6108Mpa for PMMA, Bone powder and Animal Hair respectively. On the other hand, as the filler load increases, the tensile strength of the composite decreases in the order: 49.9766>42.7583>34.7440Mpa for Bone powder , PMMA and Animal Hair respectively. The poor tensile strength of the composite could be attributed to the presence of cross-linking in the epoxy resin, a thermoset. This cross-linking prevents the filler from having maximum surface interaction with the matrix.
