Abstract:
A method of manufacturing a part made of carbon--carbon composite material, the method comprising forming a three-dimensional fiber structure, compressing the fiber structure to obtain a fiber preform of shape close to that of the part to be manufactured, holding the preform in its compressed state, and densifying the preform, the method being characterized in that:the three-dimensional fiber structure is formed by superposing layers of felt and by bonding them together by needling; thenthe fiber structure is compressed so as to obtain a preform having a fiber volume fraction of not less than 20%; andthe preform is held in its compressed state by injecting a liquid composition inside a tooling in which the preform is compressed, said liquid composition containing a bonding agent capable of bonding together the fibers of the preform.
