Effect of interfacial properties on tensile strength in SiC/Ti–15–3 composites

Effect of interfacial properties on tensile strength in unidirectional SiC/Ti–15–3 composites was discussed with varying consolidation time of the composites. The strength of composites and extracted fibers decreases with increasing consolidation time of the composites, while the strength of matrix is independent of it. Furthermore, the interfacial shear strength increases with increasing consolidation time of the composites, while the interfacial sliding stress is independent of it. Based on these experimental results, it is clear that the rule of mixtures modified with the shear transfer mechanism at the interface, characterized by the interfacial shear strength, could estimate the tensile strength of titanium matrix composites more accurately than the conventional rule of mixtures.
