摘要
碳纤维复合材料因性能优异而被广泛应用于许多尖端领域,以碳纤维增强树脂基复合材料为主要代表。然而,树脂基体自身的脆性,以及复合材料较差的层间断裂抗性仍然是阻碍碳纤维复合材料发展的瓶颈。静电纺丝是一种高效且灵活的纳米纤维制备方法,所制备的纳米纤维具有高孔隙率、低密度、高比表面积等优点,可以通过改善碳纤维表面、增强树脂基体以及两者之间的界面黏结作用,实现多种机理的层间增韧。本文从树脂基体切入,分为层间颗粒增韧、层间纤维膜增韧及复合纳米增韧三部分讨论了近三年的研究成果,并指出了层间增韧领域未来的研究方向。
Carbon fiber composites are extensively employed in cutting-edge fields due to their remarkable performance,especially resin matrix composites.However,the brittleness of the resin matrix and the poor interlaminar fracture resistance of the composite remain significant obstacles to the advancement of carbon fiber composites.Electrospun nanofibers that is a highly efficient and flexible technique offer a potential solution to these challenges.They possess advantageous properties such as high porosity,low density,and high specific surface area characteristics,which enable them to enhance interlayer toughness through multiple mechanisms,including surface improvement of carbon fibers,reinforcement of the resin matrix,and improved interfacial bonding between the two components.Electrostatic spinning technology has achieved remarkable research progress and application results in a number of fields,and has a wide range of potential applications.This article starts with an introduction to the resin matrix and then discusses the research achievements of the past three years in three parts:interlayer particle toughening,interlayer fiber membrane toughening,and composite nanotoughening,and gives insights into future research directions in the field of interlayer toughening.
