Introduction of Ceramics into Aerospace Structural Composites (L'Introduction des Ceramiques dans les Composites Utilises dans les Structures des Systemes Aerospatiaux)
Abstract
Ceramics have been considered over the last two decades as a possible alternative to refractory metals and alloys to be used as structural materials for aeronautical use. The main disadvantage of these materials is their brittleness and the very low value of the critical size of defects leading to fracture. The concept of ceramic matrix composites has been recognized as one of the ways to escape this difficulty. Extensive work has been performed to identify the mechanisms of crack propagation and general fracture for unidirectional composites, laminates or other fabrics, including the understanding of their long term response: creep and fatigue effects or environmental degradation. The Workshop which has been held by AGARD SMP at Antalya (Turkey), April 1993, aimed at reviewing the present knowledge on all these aspects.
