Moulding material (210) comprising a core layer (212), a reinforcement layer (214) provided on each surface of said core layer (212), and a layer of a surfacing material (216) provided on a reinforcement layer (214). The core layer (212) comprises a core resin material and a filler material (218). The reinforcement layer (214) comprises a fibrous reinforcement material (220) and a reinforcement resin material (222). The reinforcement layer (214) further comprises a conduit to allow gases to pass out of the moulding material via the reinforcement layer (214) during processing of the moulding material whereby the conduit structure is formed by said reinforcement material (220). |
