摘要
石墨烯因独特的二维结构与优异的力学性能成为铝基复合材料的理想增强体。随着铝基复合材料制备技术的日益成熟,石墨烯增强铝基复合材料在结构材料的广泛应用已成为研究的热点。综述了石墨烯增强铝基复合材料制备工艺的最新研究进展,重点讨论了石墨烯有效分散的方法,石墨烯铝基复合材料的组织与界面结构。研究表明,石墨烯能够显著提高复合材料的力学性能,细化基体晶粒。通过合理控制复合材料的制备工艺参数不但能够有效解决石墨烯的团聚问题,而且能避免石墨烯与基体之间界面的不利反应。最后提出了石墨烯增强铝基复合材料研究目前面临的挑战以及解决思路。
Graphene materials with unique two-dimensional structure and excellent mechanical properties have become an ideal reinforcement.With the increasing progress of aluminum matrix composites preparation,as structural materials,graphene reinforced aluminum matrix composites have attracted many interests.This paper mainly reviews the latest research progress on preparation of graphene reinforced aluminum matrix composites,and especially discusses the effective dispersion technique of graphene,meanwhile,the microstructure and interfacial structure of graphene reinforced aluminum matrix composites are also emphasized and discussed.Studies show that graphene can significantly improve the mechanical properties of composites and refine matrix grain.By controlling preparation parameters,the problem of graphene agglomeration can be effectively solved,and adverse reaction between graphene and substrate interface can be avoided.Finally,current challenges and solutions of graphene reinforced aluminum matrix composites are presented.
