Abstract
Provided are a thermosetting resin composition suitable for forming a composite material that has excellent mechanical characteristics, such as wet heat resistance and toughness, and also a prepreg using the same. The thermosetting resin composition includes at least a component [A] including thermoplastic resin particles and a thermosetting resin [B]. The component [A] includes a melt blend of at least the components [A-1] and [A-2] given below. In the particles, the component [A-1] and the component [A-2] may be in a non-compatibilized state or a compatibilized state. Component [A-1]: Thermoplastic resin insoluble in the thermosetting resin [B] Component [A-2]: Thermoplastic resin soluble in the thermosetting resin [B]
