This paper reports some fracture characterization results of hydroxyapatite (HAP)-filled poly(ε-caprolactone) (PCL). For the fracture toughness tests, the HAP concentration was steadily increased. The effect of HAP phase in PCL on the fracture and tearing toughnesses was investigated. The techniques of essential work of fracture (EWF) and tear strength were attempted. T-peel test was also used to evaluate the adhesive bond strength between HAP and PCL components using compression molded PCL-HAP-PCL laminates. Little is reported on the interfacial adhesion properties between bioactive components in scaffold development. The influence of PCL layer thickness (1.25, 2.5 and 3.5 mm) on adhesive strength between HAP and PCL was investigated. The adhesion between HAP and PCL components was found to be relatively strong; however, the thickness of PCL layers did not significantly influence the adhesive strength.
