Abstract
In this paper, the fiber/matrix interfacial frictional coefficient of continuous fiber-reinforced ceramic-matrix composites (CMCs) at room and elevated temperatures have been investigated. The fatigue hysteresis loops models considering the fiber/matrix interface friction between fibers and the matrix have been developed to establish the relationships between the fatigue hysteresis loops, fatigue hysteresis dissipated energy and fiber/matrix interface frictional coefficient. Using the experimental fatigue hysteresis dissipated energy, the fiber/matrix interface frictional coefficient of SiC/Si3N4 and SiC/SiC composites at room and elevated temperatures were obtained for different cycle numbers, interface properties and fatigue peak stresses. The effects of fiber/matrix interface bonding, fatigue peak stress, test temperature and cycle number on the evolution of fatigue hysteresis dissipated energy and fiber/matrix interface frictional coefficient have been analyzed.
