PROCEDE DE FABRICATION DE PIECES, NOTAMMENT DE DISQUES DE FREINS, EN MATERIAU COMPOSITE CARBONE-CARBONE |
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.
