Dynamic behaviour of biomaterial reinforcements in composite systems

The tension-tension fatigue behavior of hydroxyapatite (HA) particulate reinforced polyetheretherketone (PEEK) composites were investigated, with particular interest in the influence of HA surface morphology, HA loading and applied cyclic stress. Fatigue testing was carried out under load-controlled...
