Method of manufacturing parts from a composite material with carbon fibre reinforcements

摘要

The method involves making coherent fiber preform of carbon fibers presenting holes (50a) that are formed in a face of the preform. The preform is densified by chemical vapor infiltration type process to deposit material constituting a matrix. The holes having cross-section of mean dimension in the range 50-150 mm, are formed by penetrating several non-rotary elongate tools that have rough surface for breaking or transferring fiber.
