Abstract

In the present investigation, three-point bend testing was performed to characterise the mechanical properties of a bioactive composite consisting of various volume fractions of glass-ceramic apatite-wollastonite (A-W) particulate filler (10-50vol%) reinforcing a high-density polyethylene (PE) matrix (denoted as AWPEX). The effects of filler volume fraction on the yield strength, Young's modulus and strain to failure were observed. An increase in the volume fraction of glass-ceramic A-W from 10 to 50 vol% resulted in an increase in the Young's modulus from 1.1(±0.3) to 5.7(±0.3) GPa and the yield strength from 5.2(±0.7) to 13.6(±0.9) MPa. A decrease in strain to failure was observed with increasing filler content, associated with a decrease in the plastic deformation.
