Abstract
Disclosed is a microcapsule-type curing agent comprising (A) a curing agent for a thermosetting resin and (B) a thermoplastic resin dissolvable to the thermosetting resin by heating. The microcapsule-type curing agent is formed as a particle-like material in which the component (A) is coated with a layer whose main constituent is the component (B) and the mean particle diameter of which is in the range of 0.1 to 20 .mu.m. By using the microcapsule-type curing agent, a thermosetting resin composition and a prepreg which are good in storage stability at a room temperature and excellent in thermal resistance of a cured product made therefrom can be obtained. Further, a fiber reinforced composite material obtained using this thermosetting resin composition is excellent in curing uniformity and thermal resistance.
