▎ 摘　　要

NOVELTY - Preparation of graphene modified carbon/carbon composite material involves soaking carbon fiber in graphene N-methylpyrrolidone solution, sonicating, drying at 150 degrees C, heating at 260-280 degrees C, placing under carbonizing furnace at 400 degrees C under argon gas, maintaining temperature for 2 hours, raising temperature to 800 degrees C, incubating for 2 hours and cooling to room temperature. USE - Method for preparing graphene modified carbon/carbon composite material (claimed). ADVANTAGE - The graphene modified carbon/carbon composite material has high bending strength, and high fiber bundle/body interface cutting intensity.
