ABSTRACT:
A maleimide resin composition which gives a cured plastic having high toughness, high elastic modulus, high thermal resistance, high thermal decomposition resistance, low water absorption and high solvent resistance, as well as a prepreg and a fiber-reinforced plastic having the maleimide resin composition of the present invention as a matrix resin is disclosed. The maleimide resin composition of the present invention comprises a maleimide resin [A]; and a polyimide resin [B] containing a recurring unit of the formula [I] and/or [II]: ##STR1## (wherein Z represents a tetracarboxylic acid dianhydride residue) ##STR2## (wherein Z represents the same meaning as in formula [I]) said polyimide has amino groups and/or maleimide groups at the ends of the polyimide molecules.
