摘　　要：本研究自行设计研制了碳纤维增强尼龙6复合材料反应注射拉挤成型实验平台。将实验平台分为配胶系统与拉挤系统两个模块,通过对尼龙6阴离子聚合反应条件的分析及料液流量输出的计算,完成配胶系统的配置选型及拉挤单元加热模具的设计,结合碳纤维纱线的储存、预处理系统及牵引系统,完成实验平台的研制,并且通过实验平台的运转,制备出树脂固化完全且分布均匀,纤维体积含量为47.48%的碳纤维增强尼龙6复合材料平板。考虑到后续连续工业化生产需求,保证料液的持续供给,提出了一种连续在线配胶反应注射机的设计思路,为工业化生产的前期筹备工作提供参考。In this study,an experimental platform for reaction injection pultrusion of carbon fiber reinforced nylon 6 composites was designed and developed.The experimental platform was divided into two modules:the solution preparing system and the pultrusion system.Through the analysis of nylon 6 anionic polymerization reaction conditions and the calculation of feed liquid flow output,the configuration and selection of the solution preparing system and the design of the pultrusion unit heating mold were completed.The development of the experimental platform was completed in combination with the storage and pretreatment system of carbon fiber yarn and the traction system.The carbon fiber reinforced nylon 6 composite plate with complete curing and uniform distribution of resin and 47.48%fiber volume was prepared by running the experimental platform.Taking into account the demand of subsequent continuous industrial production to ensure the continuous supply of feed liquid,a design idea of continuous on-line solution preparing reaction injection machine was proposed,which provides a reference for the preparatory work of industrial production.
