Deformation and Failure Modeling of Fiber Reinforced Ceramics with Porous Matrix

A 2D reinforced carbon/carbon‐composite was investigated in tensile tests with variable fiber orientation relative to the loading direction. The experimental results from two different orientations (0° and 45°) are used to derive material parameters which are implemented into a macroscopic model. Th...

Description
Summary:A 2D reinforced carbon/carbon‐composite was investigated in tensile tests with variable fiber orientation relative to the loading direction. The experimental results from two different orientations (0° and 45°) are used to derive material parameters which are implemented into a macroscopic model. The model describes the materials response, i.e. the stress‐strain behavior and the ultimate failure of the composite, under any angle between fiber orientation and loading direction. The predicted data are confirmed by experimental results.
