A matched mould curing apparatus (10) defining a moulding cavity is provided; two sets of layers (16, 26) of curable, fibre-reinforced, thermosetting composite material are laminated on the lower forming tool (11) and upper forming tool (12). Closed-cell foam core segments (15a-15d) are provided and placed adjacent to each other on the layers (16). The core segments are oversized with respect to the nominal size determined by the moulding cavity in the closed condition, minus the thickness of the layers (16, 26) of composite material. A controlled temperature is applied firstly so as to allow plastic deformation of the core segments (15a-15d), but without closing completely the matched mould. The temperature and pressure are then applied so as to cause complete closure of the matched mould (10, 11, 12) and curing of the laminated layers (16, 26). |
