MANUFACTURE OF COMPOSITE MATERIAL

摘要

A composite material comprising reinforcing carbon fibres in an epoxy resin matrix is manufactured by stacking alternate layers of resin impregnated fibre and polyester release film, and compressing the stack between shaped formers at a temperature below the resin cure temperature. The layers are than separated and the release film discarded. After re-stacking, the fibre layers are autoclave moulded on an appropriately shaped former at a temperature at which the layers consolidate and the resin cures.
