The material is composed of previously machined glass/SiC skins which is an expanded glass foam cake forming a sandwich structure which is obtained by placing on a rigid support the elements of the sandwich structure, applying a uniformly distributed mechanical pressure to the structure and by heating to structure under air at atmospheric pressure according to a specific heating/cooling cycle aircraft. One application of this product is to load-bearing structures.

Method of forming a low-density insulating thermostructural composite

Introducing into a space delimited by the walls of a mould a sufficient quantity of a material required to obtain the final composite, placing in the material movable inserts corresponding to the hollow sections of the final piece, applying to the unit a uniformly distributed mechanical pressure under heat, extracting the material from the mould and mechanically removing the movable inserts from the material. Structural pieces formed of sandwich panels incorporating an internal stiffener.
