摘要
树脂基复合材料具有比强度高、比模量大、耐高温、耐腐蚀、质轻等诸多优点,在航天军工、生物医疗、电子封装、体育器材等众多领域得到广泛应用。石墨烯作为一种典型的二维纳米材料,凭借其独特结构以及优异的物理化学性能而备受关注。近年来的研究表明石墨烯可以通过对增强纤维改性和对基体树脂改性的方法来提高树脂基复合材料的力学性能。本文介绍了石墨烯改性树脂基复合材料的增强增韧机理,对石墨烯改性纤维(碳纤维、玻璃纤维、芳纶纤维)增强复合材料以及树脂的改性方法进行了综述;着重阐述了石墨烯改性树脂基复合材料力学性能的研究进展,分析了石墨烯改性树脂基复合材料研究中依旧存在的两大问题,即石墨烯的分散性和界面结合问题,并对石墨烯改性树脂基复合材料的未来发展前景进行了展望。
Owing to the high specific strength,large specific modulus,outstanding heat and corrosion resistance,as well as light weight,resin-composites have been widely used in aerospace and military industry,bio-medical,electronic packaging,sports equipment and many other fields.As a typical two-dimensional nanomaterial,graphene has attracted much attention due to its unique structure,outstanding physical and chemical properties.In recent years,many investigations have revealed that graphene is able to improve the mechanical properties of resin composites through fiber modification and matrix modification.In this review,the strengthening and toughening mechanisms of graphene-modified resin composites were introduced,the research progresses of graphene modified carbon fiber,glass fiber and aramid fiber were reviewed,and the research progresses of mechanical properties of graphene-modified resin composites were discussed emphatically.Finally the dispersion of graphene in matrix and its poor interfacial bonding performance with resin were systemically studied,and the future development perspective of graphene-modified resin composites was prospected.
