ABSTRACT
In this chapter, the temperature- and time-dependent FMCS of SiC/SiC composites is investigated using the energy balance approach. Effects of environment temperature on the fiber and matrix elastic modulus, fiber/matrix interface shear stress and interface debonding energy, and the matrix fracture energy are considered. Effects of the fiber volume, fiber/matrix interface properties, and matrix properties on the temperature- and time-dependent FMCS and composite internal damages are analyzed. Experimental FMCS and fiber/matrix interface debonding length of 2D SiC/SiC composites with different interphases at elevated temperature are predicted.
