Abstract:
A resin composition for a fiber reinforced composite material comprising an epoxy resin, a curing agent and an additive that changes viscoelasticity of the resin composition, said resin composition having a modulus of storage rigidity G' of 5 to 200 Pa in a temperature range of 70.degree. C. to 100.degree. C. when said G' is measured by a parallel plate rheometer at a vibration frequency of 0.5 Hz with a temperature rise of 1.5.degree. C./min from a starting temperature of 50.degree. C., said additive that changes viscoelasticity of the resin composition comprising inorganic particles of an average particle size of 40 nm or less.
