A METHOD OF MAKING A FIBER PREFORM FOR MANUFACTURING PARTS OF A COMPOSITE MATERIAL OF THE CARBON/CARBON TYPE INCORPORATING CERAMIC PARTICLES, AND PRODUCTS OBTAINED THEREBY.

摘要

One or more two-dimensional fiber fabrics of carbon or carbon precursor fibers are impregnated (58, 59) by a solution or a suspension capable of allowing a dispersion of discrete ceramic particles to remain in the fiber fabric, and a fiber preform (51) is made by superposing plies formed of two-dimensional fabric made of carbon or carbon precursor fibers, the plies being bonded to one another, and at least some of the plies being at least partially formed of a previously- impregnated two- dimensional fabric. The field of application is particularly that of friction parts made of C/C composite material with incorporated ceramic particles.
