ABSTRACT:
A fiber-reinforced resin composition, which comprises:
an epoxy resin having at least two epoxy groups in the molecule,
a polymerizable unsaturated group-containing epoxy compound of the following general formula [I], ##STR1## wherein R.sup.1 is H or CH.sub.3, R.sup.2 is an alkylene group having 1 to 20 carbon atoms, and n is an integer of 0 to 20,
a liquid carboxylic acid anhydride containing a monofunctional carboxylic acid anhydride and/or a polyfunctional carboxylic acid anhydride obtained by reacting a lower aliphatic polyhydric alcohol with a trimellitic acid or a derivative thereof,
a curing promoter,
a radical polymerization initiator, and
a fiber,
the glass transition temperature (Tg, .degree.C.) and breaking strain (E, %) of a cured product of said composition satisfying the following formulae:
