Abstract

See full text

An recycled composite material is disclosed, which is prepared by using as a raw material a waste composite material which comprises a matrix component and carbon fibrous structures added to the matrix, and adding an additional matrix component which is homogeneous and/or heterogeneous with the matrix of the spent composite material, and then kneading them together; wherein the carbon fibrous structure comprises a three dimensional network of carbon fibers, each carbon fiber having an outside diameter of 15-100 nm, and a granular part, at which the fibers are bound in a state that the carbon fibers extend outwardly therefrom, and wherein the granular part is produced in a growth process of the carbon fibers. The recycled composite material performs much the same with the original composite material, and is produced briefly at a low cost.
