▎ 摘　　要

NOVELTY - The method involves stacking multiple graphene oxide films in thickness direction to form a layer structure. A carbon fiber wire is used to pass through the stacked layers of graphene oxide film in the thickness direction. The stacked multi-layer graphene oxide membrane is placed with carbon fiber wire in the device for carbonization and graphitization treatment to obtain the carbon fiber-reinforced graphene foam blocks. USE - Method for preparing carbon fiber reinforced graphene foam block used for preparing thermally conductive gasket (all claimed). Uses include but are not limited to microelectronic devices, flexible sensor device, flexible energy storage device, intelligent garment material, and aerospace. ADVANTAGE - The process is simple and easy to operate. The internal bonding force of the graphene foam blocks is improved. The carbon fiber in the foam block is in a high orientation state, thus improving the thickness direction of the heat conducting performance, and removing the graphene two-dimensional heat conducting material defect. Thus, the whole heat conducting and radiating performance is improved. The size and thickness of the foam blocks are easy to control and are suitable for die-cutting process of various special-shaped elements. The market demand is satisfied, and the application prospect of graphene is widened. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a carbon fiber reinforced graphene foam block; and (2) a thermally conductive gasket. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the carbon fiber reinforced graphene foam block. 1Graphene layer 2Carbon fiber
