Abstract: A carbon fiber has a coaxial stacking morphology of truncated conical tubular graphene layers, wherein each of the graphene layers includes a hexagonal carbon layer and has a large ring end at one end and a small ring end at the other end in the axial direction. When the carbon fiber is subjected to a heat treatment in a non-oxidizing atmosphere, the large ring ends of each two of the hexagonal carbon layers are linked by layer link sections in at least one of groups of the hexagonal carbon layers arranged in an axial direction, and an outer surface is closed to have a multi-semiring structure in cross section. When the carbon fiber is then subjected to a heat treatment in an oxidizing atmosphere, the layer link sections are released, whereby the edges of the hexagonal carbon layers are exposed at the large ring ends in a regularly arranged manner.

Abstract: An electrode material for an electric double layer capacitor having a carbon fiber as an essential material. The carbon fiber has a coaxial stacking morphology of truncated conical tubular graphene layers, and each of the truncated conical tubular graphene layers includes a hexagonal carbon layer. Edges of the hexagonal carbon layer are exposed. The exposed edges of the hexagonal carbon layers have a high degree of activity and can be modified with functional groups such as nullCOOH, nullCHO, or nullOH. This enables use of the carbon fiber as the electrode material. The specific surface area of the surfaces on which the edges are exposed is extremely large, whereby a large-capacitance electric double layer capacitor can be formed.

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 material 1, an uncured resin 4 having carbon nanofibers 5 dispersed therein is impregnated into a number of fiber reinforcing plies 2a laid one upon another. Upon curing the resin 4, the strength of the matrix 3 itself is increased through the carbon nanofibers 5 dispersed in the resin 4. Moreover, the fiber reinforcement 2 and the resin 4 are joined together strongly by the carbon nanofibers 5, and hence the strength of the composite material, for example the compressive strength, which hitherto has been dependent on the strength of the resin 4 only, is improved.
