Localized mechanical properties of composite components (fiber, matrix, and interface) are critical parameters bridging the composition, microstructure and macro-mechanical performance of continuous fiber-reinforced ceramic matrix composites (CFRCMCs). However, they are difficult to be acquired and decoupled from bulk composites based on the traditional macro-mechanical testing techniques, due to their limited testing volumes and complex heterogeneous composite structures. The above questions has been solved recently by novel nano/micro mechanical testing and focused ion beam milling (FIB) techniques, which provide powerful tools to quantify the micro-mechanical properties of CFRCMCs. In this paper, recent progress in micro-mechanical properties of CFRCMCs was firstly reviewed, with special emphasis on the in-situ modulus and toughness of ceramic fibers and matrix, and the shear property of fiber/matrix interface. Following that, a criterion based on the He-Hutchinson cracking model was proposed to predict the macro mechanical performance of CFRCMCs by using those micro-mechanical parameters.
