Several different hybrid laminated composites comprised of alternating layers of dense ceramic sheets (either SiC or Si 3 N 4 ) and fiber‐reinforced ceramic‐matrix‐composite (CMC) layers (Nicalon fibers with either glass or glass‐ceramic matrices) have been fabricated and characterized. The effects of the reinforcement architecture (unidirectional vs cross‐ply) and the relative volume fractions of the phases on the tensile and flexural properties have been examined. Comparisons have been made with the properties of the constituent layers. Rudimentary models have been developed to describe the onset of cracking and for the minimum volume fraction of CMC required to develop multiple cracks and thus obtain a high failure strain.
