Silicon Carbo-Nitride Ceramic Matrix Composites by Polymer Pyrolysisors were optimized with respect to ceramic yield and minimum bloating during pyrolysis. Solution infiltration of stacked Nicalon SiC fibre weaves was performed. Repeated impregnations/pyrolyses yielded fairly strong composites exhibiting non-brittle fracture behaviour, especially when a polymer free

Resistance to Crack Growth in Fibre Reinforced Cement: Effect of Fibre Propertiesuring crack extension in this type of composite is microcracking ahead of the crack tip. This phenomenon is characteristic of a cement matrix, containing many pre-existing defects which will propagate during loading. Its effects can be calculated by applying linear elastic fracture mechanics to the

Nevertheless, significant progress has been made by polymer composites in aircraft structures, aero propulsion and marine applications and by ceramic materials in electronic and structural applications.
