Abstract

The results of a large experimental campaign concerning the mechanical behavior of SiC/SiC composites tubes under uniaxial and biaxial loadings (both tension-torsion and tension-internal pressure) are presented. The anisotropy of the elastic moduli, damage onset and failure properties has been characterized. The orientation of matrix cracking was analyzed, based on surface observations, and its connection to the macroscopic stress-strain response provides important insight into the underlying deformation mechanisms. However, the macroscopic behavior still exhibits unexplained features, and mechanisms specific to the textile architecture are proposed.
