AbstractHydroxyapatite (HA) reinforced polysulfone (PSU) composite is being developed as a new bioactive material for hard tissue replacement. In the current investigation, the fatigue performance of this composite was assessed under different combinations of axial and torsional stresses. It was found that the fatigue life of unfilled PSU and HA/PSU composite was reduced with an increasing shear stress in the biaxial stress condition. The addition of particulate HA in the polymer led to a shorter fatigue life of composite in low shear stress conditions. However, in high shear stress conditions, the effect of shear stress became dominant and the fatigue life of unfilled PSU and HA/PSU composite was similar.
