A shaped moulding is formed from a laminate composite material of aligned continuous glass fibres in a matrix of a thermoplastic material, by laying down strips of the composite material in a chamber defined between a first silicone sheet and a second silicone sheet. The chamber is sealed and evacuated to form a body of the composite material trapped between the silicone sheets, this body being heated and then pressure formed on a mould relief whilst the body is allowed to cool. The body is preferably sealed using male and female interlocking silicone extrusions which are glued between a frame and the respective silicone sheets, a vacuum being applied through one of the extrusions which are glued between a frame and the respective silicone sheets, a vacuum being applied through one of the extrusions using a vacuum pump to form the sealed, evacuated body. The body is preferably heated by placing it in an infrared oven before forming the desired shaped moulding using a vacuum forming machine. This method enables the rapid moulding of a laminate composite material, the integrity of the glass fibres being maintained while moulding relatively complex shaped mouldings.
