RECYCLED COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a recycled composite material which can exhibit the approximately same characteristics as those of original composite material and can simply be produced at a low cost.

SOLUTION: This recycled composite material is characterized by adding and kneading the same or different kind of matrix as that of matrix contained in a waste of a composite material to the waste of the composite material containing a carbon fiber structure in the matrix as a raw material. The carbon fiber structure exhibits a three-dimensional network state composed of carbon fibers having an outer diameter of 15 to 100 nm, and has granular portions in which a plurality of the carbon fibers are bound to each other in a form that the carbon fibers are extended, and the granular portions are formed in a process for growing the carbon fibers.
