摘要 |
<p>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.
