Summary

The mechanical behavior of Nicalon™ SiC fiber-reinforced calcium aluminosilicate composite laminates was examined. The fiber/matrix interfacial strength was measured from various indentation techniques. Tension tests were carried out on unidirectional and 0°/90°/0° cross-ply laminates. The cross-ply laminates exhibited a sequence of failures, including transverse and longitudinal cracking of the 90° ply and matrix microcracking in the 0° plies. The transverse cracks were evenly spaced, and their onset occurred at a strain below that of the matrix microcracking. The effect of laminate geometry on the transverse cracking behavior and interactions among the various laminate failures were investigated.
