Abstract

Because of a significant mismatch between the thermal expansion coefficients of the fiber and the matrix, the interfacial thermal residual stress (TRS) in SiC/Ti-15-3 composites is induced during cooling procedure when continuous SiC fiber reinforced titanium-based composites are manufactured. The distance between fibers varies randomly. The TRS in the region nearby one fiber will be affected by the neighbor fibers. This paper aims to study the fibers interactional influence of neighbor fibers interfacial thermal residual stress. After pushing out neighbor fibers, TRS is measured using micro-moiré interferometry. This process has also been numerically simulated using the finite element software.
