3 Fabrication of Oxide-Matrix Composites,in ceramics increases with density. As an exception, the fabrication of the porous-matrix composites and hybrid ceramic composites may usually require no fiber coating and no complicated consolidation step.

Instead, a moderately high mechanical strength and high toughness in the composites were given greater priority.

4 Tailoring and Control of Interphase,s, leading to fiber pull-out and consequently to damage tolerance of the composite. That means, by crack bridging, crack blunting and crack deflection mechanisms oxide CMCs tolerate fracture which otherwise, in monolithic ceramics, leads to catastrophic failure.

5 Porous matrix composites,Synthesis of an effective fiber coating may require higher temperatures which partly degrade the fiber. Moreover, full-coverage of fiber surface with a coating layer which serves as an interphase in the composites may be costly and difficult to realize.
