▎ 摘　　要

NOVELTY - The preparation method involves introducing Z puncture in the two-dimensional carbon fiber cloth carbon fiber preform in the fiber. The carbon fiber preform in vivo reduction of graphite oxide in CVI deposition furnace is used to produce graphene. The carbon or carbon composites are prepared via densification process. USE - Preparation method of graphene modified 3D charcoal. ADVANTAGE - Improves the productivity of composite materials, thus achieving a variety of sizes and dimensions of carbon fiber preform densified favor large-scale production.
