Tensile Deformation of SiC/Ti-15-3 Laminates


The damage mechanisms of a laminated, continuous SiC fiber-reinforced Ti-15-3 composite were investigated. Specimens consisting of unidirectional as well as cross-ply laminates were pulled in tension to failure at room temperature and 427°C and subsequently examined metallographically. Selected specimens were interrupted at various strain increments and examined to document the development of damage. When possible, a micromechanical stress analysis was performed to aid in the explanation of the observed damage. The analyses provided average constituent microstresses and laminate stresses and strains. The damage states were found to be highly influenced by the fiber architecture.
