Numerical Simulation of the Tensile Behavior of 2D-SiC/SiC Cross-Ply Laminates

Abstract

A numerical tool has been developed in order to predict the influence of the main processing parameters on the mechanical behavior of SiC/SiC [0° ,90°] laminates. The contrast between the brittle properties of 90° plies and the damage properties of 0° plies has been taken into account as well as the particular morphology of this type of composite processed by chemical vapor infiltration. The model which has been proposed represents the different features and sequences of laminate damage behavior.

Influence of the fiber volume fraction and the fiber Weibull modul on the behavior of 2D woven SiC/SiC ? a finite element simulation

“…Within a micromechanical model all considerations are restricted to a so called unit cell. In the current study a three dimensional unit cell is used which regards -unlike the commonly used plane unit cells [1], [2] -the waveness of the fiber bundles in both directions. The numerical evaluation of the model is accomplished by using the finite element method (FEM).…”
