COMPOSITE REINFORCING MATERIAL AND METHOD OF PRODUCING A COMPOSITE REINFORCING MATERIAL

摘要

Provided is a composite reinforcement raw material having excellent mechanical strength. A composite reinforcement raw material in which at least a reinforcement raw material and a graphenoid separated from a graphite-based carbon raw material are dispersed in a base material, the composite conduction raw material characterized in that the graphite-based carbon raw material has a rhombohedral-crystal graphite layer (3R) and a hexagonal-crystal graphite layer (2H), and the ratio Rate (3R) defined by (Equation 1) by X-ray diffraction analysis of the rhombohedral-crystal graphite layer (3R) and the hexagonal-crystal graphite layer (2H) is 31% or higher. (Equation 1): Rate (3r) = P3/(P3 + P4) x 100. Here, P3 is the peak intensity of the (101) face in X-ray diffraction analysis of the rhombohedral-crystal graphite layer (3R), and P4 is the peak intensity of the (101) face in X-ray diffraction analysis of the hexagonal-crystal graphite layer (2H).
