▎ 摘　　要

NOVELTY - The method involves forming a first uniformly oriented graphene layer in metal matrix material to form a first graphene metal matrix composite (MMC) layer. Graphene nanoplatelets (120) with thickness of less than 100 nm is provided. A second uniformly oriented graphene layer comprising the nanoplatelets oriented in first direction is formed. The second graphene layer is formed in the metal matrix material to form a second graphene MMC layer. The first and second graphene MMC layers are stacked to form a graphene MMC (100). USE - Method for forming a graphene MMC into heat conducting components such as heat spreaders, for providing cooling to an electronic and electrical equipment and a semiconductor device e.g. microprocessor, power inverter/converter, solid state switch, application specific integrated circuit (ASIC), graphics accelerator chip, and insulated gate bipolar transistor (IGBT). Can also be used for avionics chassis, equipment enclosures, cold plates, rack, trays, shelf, heat sinks, heat exchanger, radiators, and heat pipes. ADVANTAGE - The method enables providing the MMC with improved thermal conductivity and reduced mechanical stress issues as compared to MMC's with graphite, and providing a reduced weight thermal management system. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene MMC. Graphene MMC (100) Metal matrix (110) Graphene nanoplatelets (120) Horizontal grids (122) Vertical grids (124)
