PURPOSE:To shorten the molding time and reduce the leakage of uncured resin during molding by a method wherein a mixture, the composition of which consists of specified quantities of epoxy, carboxylic acid anhydride, chrome compound and tertiary amine compound, is used as matrix resin. CONSTITUTION:One to five wt% of active chrome compound is added as curing accelerator to a conventional mixture, which consists of 40-60 wt% of epoxy, 40-60 wt% of carboxylic acid anhydride and 1-5 wt% of tertiary amine compound, in order to be used as matrix resin. The active chrome compound is available on the market in the form of a mixture with tertiary amine compound such as benzyledimethylamine or the like under the trade name of ATC-3 or the like, and it is a curing accelerator effective for curing the conventional epoxy-acid anhydride-based thermosetting resin in a short period of time than ever.
