Abstract

Articles of resin optionally reinforced with a material covered with a layer of a similar resin, opt. reinforced, are formed in a press under vacuum. The resin is moulded in a liquid state at a temp. suitable for hardening. Moulding takes place under vacuum between a fixed bottom platen and a flexible top platen which is convex and first applies pressure along a line gradually extending the area as air is removed from the moulding. The top platen may be of aluminium backed by a corrugated sheet. The process is for making sandwich material of large area particularly in polyester resins.
