Process for fabricating a tubular body with a metal matrix composite insert

摘要

The tubular component manufacturing process includes a stage in which a layer (21) of coated filaments is wrapped round a metal mandrel (24). Each filament comprises a ceramic fiber coated with metal and bonded together at welded points, and the wrapping is carried out by starting with a triangular corner of the layer, which is then wound round the mandrel in a spiral. This is followed by at least one additional supplementary layer, after which the covered mandrel is inserted in a metal sleeve and subjected to an isostatic compaction while hot.
