COMPOSITE MATERIAL WITH AN ALUMINOSILICATE MATRIX, SUCH AS BARIUM ALUMINOSILICATE 'BAS', REINFORCED WITH METAL OXIDE REINFORCEMENTS, AND ITS PROCESS OF MANUFACTURE

摘要

A composite material consisting of a matrix made of at least one aluminosilicate notably selected from barium aluminosilicate BAS, barium and strontium aluminosilicate BSAS, strontium aluminosilicate SAS, and mixtures thereof, reinforced by reinforcements made of at least one metal or metalloid oxide, the expansion coefficient of which is close to that of said at least one aluminosilicate. A method for preparing said composite material. A composite material according to the invention notably finding its application in the aeronautical or aerospace field, for example for the manufacture of radomes.
