Ceramic composite materials with high mechanical and heat resistance and their preparation

摘要

The invention relates to ceramized composite materials comprising a substrate formed of weavable ceramic fibres with high thermomechanical properties and a matrix formed from a ceramic oxide selected from the group comprising silica, chromic oxide and magnesium oxide, the cohesion of the oxide particles being such that it permits, under stress, microfissurization which progresses to the level of the fibres.
