Determination and modelization of mode I interlaminar fracture thoughness on 2D woven oxide/oxide composite using double cantilever beam test

Abstract

Ceramic Matrix Composites are light materials with excellent mechanical properties at high temperature, which make them potential candidates for such industrial applications. Specifically, laminated Oxide/Oxide CMCs are relevant for moderate thermo-mechanical loadings because of the advantageous trade-off between their mechanical properties and their cost. For such laminated composite materials, study the initiation and propagation of delamination between plies remains a key point in order to perform relevant designs of industrial composite structures. Nevertheless, the characterization of the initiation and propagation of delamination in Oxide/Oxide composites are, to the author’s knowledge, not much studied in the literature. Therefore, this study focuses on the characterization and modelling of the delamination propagation in mode I for 2D woven Oxide/Oxide ceramic matrix composites.
