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 material1,an uncured resin4having carbon nanofibers5dispersed therein is impregnated into a number of fiber reinforcing plies2alaid one upon another. Upon curing the resin4,the strength of the matrix3itself is increased through the carbon nanofibers5dispersed in the resin4.Moreover, the fiber reinforcement2and the resin4are joined together strongly by the carbon nanofibers5,and hence the strength of the composite material, for example the compressive strength, which hitherto has been dependent on the strength of the resin4only, is improved.
