method of producing a verbundwerkstoffteils, particularly with coal or feuerfestfaserstruktur and coal or keramikmatrix.

摘要

Manufacture of a part made of composite material by formation of a fibrous reinforcing texture (10) and densification of the texture by chemical infiltration in vapour phase of the material constituting the matrix of the composite within the porosity of the texture. Before densification, the texture is separated from an adjacent structure, especially an adjacent surface of a tool (12, 14) in which the texture is maintained, or another texture, by means of an interposed layer (20) of fabric made of a refractory material which has an expansion coefficient differing from that of the constituent material of the texture. …IMAGE…
