Description

The major role of the fiber-matrix interphase in ceramic matrix composites (CMC) is to increase the composite fracture resistance; thus the properties of these materials are dominated by the interphase. To achieve this, the interphase is designed to provide friction sliding contact between fiber and matrix, which prevents fracture of fibers due to matrix cracking [1,2]. Due to the relatively low stiffness of the fiber-matrix interphase compared to fiber and matrix, the interphase also has a dominant effect on the transverse and shear stiffnesses of CMC materials [3]. Therefore, to obtain optimal performance in CMC materials quantitative characterization of the fiber-matrix interphase is necessary.
