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