PURPOSE:To prepare the subject molded product suitable for automobile parts, electrical parts, etc., and having good moldability and high filling density by mixing an epoxy resin having a specific viscosity and a liquid carboxylic anhydride curing agent with a curing accelerator and immediately pouring the mixture into a mold. CONSTITUTION:(A) 100 pts.wt. of an epoxy resin having a viscosity of 3000cps at 25 deg.C, (B) a liquid carboxylic anhydride curing agent comprising (i) a liquid monofunctional carboxylic anhydride (e.g. 3-methyltetrahydrophthalic anhydride) having a viscosity of 500 deg.C at 25 deg.C, (ii) a lower aliphatic polyhydric alcohol (e.g. 2-10C alcohol) and (iii) a liquid carboxylic anhydride curing agent comprising 2-80wt.% (based on the component i) of trimellitic anhydride, (C) a curing accelerator and preferably 5-70mol% (based on the resin components) of a fiber reinforcing material are mixed with each other and immediately poured into a mold to provide the objective molded product. |
