Micromechanical model of 3D cross-ply copper matrix composite reinforced with SiC fibres

A 3D cross-ply micromechanical model is used to analyse the thermomechanical behaviour of copper matrix composite reinforced with SiC fibres, when subjected to cyclic loadings at high temperature. The copper matrix composite is reinforced with 45% fibre volume fraction. A cohesive model is employed to capture the influence of the debonding interface in the composite, during the consolidation and subsequent thermal and mechanical loading.
