A material model for predicting the unknown elastic properties of the chemical vapor infiltrated carbon felts is proposed. Representative volume element of the studied material includes pyrolytic carbon matrix, randomly distributed carbon fibers (carbon felt) and pores. The homogenization procedure for this composite consists of two steps: (1)(More)
Mechanical behavior of multi-phase composites is crucially influenced by volume fractions, orientation distributions and geometries of microconstituents. In the case of carbon–carbon composites manufactured by chemical vapor infiltration, the microconstituents are carbon fibers, pyrolytic carbon matrix, and pores. The local variable thickness of the(More)
