A process for making a cured plastics moulding by introducing a pre-heated curable resin composition to a hotter mould which is at a temperature high enough to initiate curing of the resin, and supplying further resin under pressure to compensate for shrinkage of the composition wherein the curable resin is a formulation comprising an aromatic glycidyl ether epoxy resin, an inert filler, a quaternary ammonium or phosphonium salt as accelerator, 0.5-1.2 mol per mol epoxy of a saturated cycloaliphatic anhydride and a polycarboxylic acid preferably derived from the reaction of a polyol, this acid being present at a level of 0.05-0.5 mol carboxyl per mol epoxy. |
