Abstract
The resin in a fiber-reinforced resin material that uses a single fiber reinforcing ply or a number of fiber reinforcing plies for reinforcing the resin material is reinforced by dispersing carbon nanofibers therein, whereby a fiber-reinforced composite resin material having improved strength such as compressive strength is provided. In a carbon nanofiber-dispersed resin fiber-reinforced composite materialan uncured resinhaving carbon nanofibersdispersed therein is impregnated into a number of fiber reinforcing plieslaid one upon another. Upon curing the resinthe strength of the matrixitself is increased through the carbon nanofibersdispersed in the resinMoreover, the fiber reinforcementand the resinare joined together strongly by the carbon nanofibersand hence the strength of the composite material, for example the compressive strength, which hitherto has been dependent on the strength of the resinonly, is improved.
