PROCESS FOR MANUFACTURING PARTS, IN PARTICULAR BRAKE DISCS, OF CARBON-CARBON COMPOSITE MATERIAL

摘要

A textile three-dimensional structure is formed by superposing felt layers and binding them together by needle bonding, then it is compressed so as to obtain a preform having a fibre volume ratio not less than 20 %. The preform is maintained in its compressed state by impregnating it with a liquid composition containing a binding agent for binding the preform fibres together. The resulting consolidated preform is densified for instance by chemical infiltration in vapour phase.
