Procedure for binding at least two composite bodies, the matrices of which consist of ceramic fibre reinforced, ceramic or glass ceramic material

摘要

The invention relates to a method of joining at least two parts made of a composite material comprising a ceramic or glass-ceramic matrix reinforced by ceramic fibres. The object of the invention is to make a continuous connection between these parts. This object is achieved with the aid of a method consisting in: - bringing two of the parts (1, 11; 3, 31) along their respective edges (5) to be joined; - making a joint (8) between these two parts, by stitching, with a tie (9, 10), the ceramic fibres (71, 73) coming from each of the parts (1, 1'; 3, 3') to be joined; and - heating this joint using means allowing extremely localised and powerful heating until the two parts (1; 3) are bonded together. This method is especially intended for joining turbojet parts. IMAGE
