Abstract
Monolithic ceramics are highly sensitive to process and service related flaws, making them inherently brittle. Due to their low toughness, these materials fail catastrophically. Continuous fiber-reinforced composites usually provide a significant amount of toughness as well as avoid catastrophic failure. The interface between the fiber and the matrix can significantly affect the mechanical properties of the composite. A very strong interface yields brittle fracture as the crack propagates through the matrix and fiber. In contrast a very weak interface between the fiber and matrix is incapable of transferring the load from the matrix to the fiber and hence the properties of the fiber are not used effectively and the mechanical properties are similar to that of a porous material. Therefore the design and optimization of the interface properties are of vital importance for fabricating ceramic composites with superior mechanical performance. Before these coated ceramic composites can be used in primary structural applications, it is necessary to obtain the fundamental properties of these materials. This paper presents a study on the effects of fiber coating thickness and fiber volume fraction on the transverse mechanical properties of coated ceramic composites.
