'A method of manufacturing a fiber-reinforced composite material for resin composition, prepreg, fiber-reinforced composite materials, honeycomb structure'

摘要

It is characterized that the storage rigidity factor G u2032 in the whole range of 70 to 100 u00b0 C. is measured in a parallel plate having a vibration frequency of 0.5 Hz, while the component [a] epoxy resin, [b] hardener and [C] additive are essential components, and are heated at 50.degree. C. to 1.50.degree. C. in the range of 5 to Resin composition for fiber reinforced composite material and prepreg using the same. The prepreg is self-adhesive to the honeycomb core and reduction in porosity when the skin panel is used, excellent surface smoothness, suitable tack and drapability, and can be used for aircraft, automobile, industrial use, especially aircraft structural materials.
