Abstract
A preform for fiber rein-forced composite material producing includes a thermosetting resin composition and a dry reinforcing fiber base, the thermosetting resin composition characterized in that when subjected to dynamic viscoelasticity measurement at a traction period of 0.5 Hz while heating at a rate of 1.5° C./min, a temperature change ΔT is 45° C. or less as complex viscosity η* decreases from 1×10Pa·s to 1×10Pa·s.
