Compression moulding of composite or laminated articles, especially skis, having a fibre-reinforced resin exterior (32), (33), (34) and cellular rigid core (31), the special feature of which is that the required moulding pressure is developed by the foaming of the resin of the core (31) when this is heat-hardened. The bottom of the mould (1) is first lined with a resin-impregnated fibre sheet (32) which may have special sliding edges (36), after which the core material (31) is introduced and covered with a further layer (33). Edge protection (34) may be arranged and other layers (32) enclosing the long sides of the core (31). The mould cover is then fixed to the mould, and the whole assembly heated to cause the core (31) to foam and expand. |
