Document Type and Number:
WIPO Patent Application WO/2011/040602
Kind Code:
A1
Abstract:
A method for manufacturing a fibre-reinforced composite material with good mechanical properties and high heat resistance, such that a plaster mold can be used for initial curing. A fibre-reinforced prepreg obtained by impregnating reinforced fibres with an epoxy resin composition which contains a triphenylmethane type epoxy resin (A), N, N, N', N'-tetraglycidyl diaminodiphenylmethane (B), and diaminodiphenylsulfone (C), undergoes an initial curing at 110-130°C and furthermore undergoes a second curing at a temperature not less than the temperature of the initial curing.
