A composite material consisting of a matrix made from at least one aluminosilicate chosen, in particular, from barium aluminosilicate (BAS), barium strontium aluminosilicate (BSAS), strontium aluminosilicate (SAS), and the mixtures of same, reinforced with reinforcements made from at least one metal oxide or metalloid oxide of which the expansion coefficient is close to that of the at least one aluminosilicate. A method for preparing said composite material. A composite material according to the invention, which can be applied, in particular, in the fields of aeronautics or aerospace, for example for the production of radomes. |
