摘要
热塑性树脂分子量大,熔体黏度高,采用热熔方法制备复合材料存在树脂流动性差、微观尺度上易形成复合缺陷的问题。采用原位聚合方法制备热塑性复合材料,不仅可以避免上述问题,还能够沿用热固性复合材料的成型方法,进而实现热塑性复合材料的高效率、低成本制造,因此原位聚合热塑性复合材料在复合材料应用领域具有广阔的应用前景。围绕几种原位聚合热塑性树脂,本文阐述了其复合材料性能及成型工艺的研究现状,并针对目前存在的问题,提出了4个研究方向:改性工艺与成型工艺的耦合、聚合环境洁净度和聚合反应对杂质的敏感性的控制、聚合反应放热温度的控制、液体成型树脂适用期的调控。
The thermoplastic resin has a huge molecular weight and high viscosity of its melt,so there are some problems in the preparation of composite materials by hot melting method,such as poor fluidity of resin and easy formation of composite defects on the microscopic scale.Using in-situ polymerization to prepare thermoplastic composites can not only avoid the above problems,but also use the forming method of thermosetting composites,so as to achieve high efficiency and low-cost manufacturing of thermoplastic composites.Therefore,in-situ polymerization thermoplastic composites have broad application prospects in the field of composite materials.Based on several in-situ polymerized thermoplastic resins,this paper describes the research status of composite material properties and forming processes,and puts forward four research directions in view of the existing problems:Coupling of modification process and forming process,control of environmental cleanliness of polymerization and sensitivity of polymerization to impurities,control of heat release temperature of polymerization reaction,regulation of pot life of resin.
