Textile Reinforcements: Architectures, Mechanical Behavior, and Forming
The mechanical properties of the matrix of the ceramic matrix composites (CMCs) are higher than those of the fibers. This chapter concerns the analysis of the architecture and mechanical properties of the textile reinforcement. In particular, the forming process is analyzed and modeled. This forming gives a preform in which the ceramic matrix is introduced by chemical vapor infiltration (CVI). This manufacturing process corresponds to liquid composite molding (LCM) in case of organic matrix composites. The principal experimental tests for the determination of tensile, in‐plane shear, bending, and compaction properties are described. Then a 3D hypoelastic model for textile reinforcement is presented. The main point in such a model lies in the follow‐up of the fiber directions. Finally, two approaches for the simulation of textile reinforcement forming are described. The first is based on the hypoelastic model and the second uses semidiscrete shell finite elements.
