CARBON-CARBON COMPOSITE MATERIAL

摘要

A method of manufacturing a carbon-carbon composite material comprises providing within an enclosure that defines a non-oxidising environment an array of carbon fibres and polymeric material of the kind which yields greater than 60 % by weight of carbon when heated to at least 600 DEG C, and then subjecting the combination of materials to a substantially uniaxial compressive mechanical load whilst maintained in the enclosure at above 600 DEG C for sufficient time to consolidate the materials and to substantially wholly carbonise the polymeric material. The carbon fibres preferably are of a length at least 10 mm.
