Binder resin composition for preform, binder particle, reinforcing fiber base, preform and fiber reinforced composite material

摘要

(G * at Tg + 30 deg. C + G * at 80 deg. C) of 10 to 300, a Tg of 50 to 100 deg. C, a complex modulus of elasticity G * measured by dynamic viscoelasticity measurement of 10 to 500 kPa at Tg + And the viscosity change is monotonously decreased when the temperature is raised to 200 占 폚. A binder resin composition which is excellent in storage stability at room temperature and excellent in inter-layer interlayer adhesion at a low temperature and which can exhibit stable adhesiveness even when there is uneven temperature at the time of forming a preform, a reinforcing fiber base material, a preform, to provide.
