Influence of fibre properties on the mechanical behaviour of unidirectionally-reinforced ceramic matrix composites

Tensile tests on unidirectionally-reinforced ceramic matrix composites have been simulated using a micromechanical approach based on a shear-lag model and the chain-of-bundles theory. The model presented takes the probabilistic nature of the constituent properties into account. The results of the simulation have been compared with experimental data from literature in order to obtain information about the in-situ properties of the constituents and the influence of the fibre properties on the composite behaviour.
