The sleeve is made of a composite material. The drive shaft may be made from a composite material or a metal. The composite material is chosen from a composite of carbon-carbon fibre (CFC), silicon carbide - silicon carbide (SiC - SiC) and incorporates fibres woven in at least two directions. The sleeve may also be coated with a metal or ceramic. |
