Review on interfacial properties of SiC_f/SiC composites for gas turbine engines

초록

The mechanical behavior of SiC fiber-reinforced SiC composites (SiCf/SiC composites) is influenced by the interfacial properties between the matrix and the fiber. To enhance the performance of SiCf/SiC composites, it is essential to control the interfacial bonding strength by understanding the properties of the interface. This paper reviews how the interfacial properties between the fiber and matrix affect the cracking behavior of SiCf/SiC composites. It investigates the mechanical properties of SiCf/SiC composites in relation to the thickness and microstructure of the interphase. The paper also explores methods for forming an interphase on fibers with complex shapes and summarized techniques for quantifying the crystallization of the formed interphase.
