石墨烯具有125 GPa的高断裂强度，使其成为复合材料的理想增强材料。采用片状粉末冶金法制备了石墨烯纳米片增强铝基复合材料。仅用0.3 wt.%的Al增强的Al复合材料的拉伸强度达到249 MPa。GNS，这是62%的增强比未增强的Al基体。沿着对GNS/Al复合材料的强化机理进行了讨论。(C)2012 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Graphene has a high fracture strength of 125 GPa, making it an ideal reinforcement for composite materials. Aluminum composites reinforced with graphene nanosheets (GNSs) were fabricated for the first time through a feasible methodology based on flake powder metallurgy. The tensile strength of 249 MPa was achieved in the Al composite reinforced with only 0.3 wt.% GNSs, which is 62% enhancement over the unreinforced Al matrix. The relevant strengthening mechanisms involved in the GNS/Al composites were discussed along with experimental procedure. (C) 2012 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
