Processing by tape casting and mechanical behaviour of aluminous cement-based matrix alumina fibers composites

The present work concerns the mechanical behaviour of aluminous refractory cement and Fontainebleau sand matrix reinforced by mineral long fibres. The results concern the matrix and 1D stratified composites obtained by tape casting. By using refractory alumina fibres, the effect of fibre reinforcement is evidenced: the 4-points flexural strength is increased by a factor 3 compared to the matrix alone and the mechanical behaviour is non-brittle with a large non linear section.
