| Summary | The tensile test was carried out for unidirectional reinforced SiC/Al composite, which was fabricated by hot press and had different interfacial shear strengths. A Monte-Carlo simulation based on the elastic-plastic finite element method with interfacial layer around the fibers was performed. Effect of interfacial shear strength on composite strength and reliability was investigated. The results show that composite strength and Weibull shape parameter increase as the interfacial shear strength increases. The interfacial shear strength contribution to composite strength and reliability effectively is till near by the shear strength of the matrix. It is concluded that the strength and reliability is closely related to the fiber fracture process. |
