Abstract
Symmetric (0°/90°) composite laminates consisting of SiC fibers in a lithifum aluminosilicate matrix have been tested intension and flexure. The various modes of damage, consisting of matrix cracks, delamination cracks, and fiber bundle failure, have been examined and related to features of the stress‐strain curves. The materials exhibit a relatively lower shear strength (20 MPa), measured in flexure, than tensile strength (200 MPa), because of the formation of matrix microcracks. The stress‐strain characteristics of the laminates are shown to be predictable, based on strength measurements obtained on the individual laminate layers, in conjunction with knowledge of the residual stresses.Keywords
