中文摘要： 随着复合材料构件的大型化，热压罐固化工艺控制难度大、成本高的问题越来越突出。电子束固化复合材料工艺简单，制备的复合材料构件综合性能优于传统热固化复合材料，是替代热压罐工艺的下一代低成本复合材料制造技术。但较小的层间剪切强度是制约电子束固化复合材料工业化应用的技术瓶颈。项目组提出采用微波激发分子高频振动摩擦生热原理强化电子束固化中树脂分子与纤维界面相互作用的新技术思路，解决电子束固结复合材料构件层间剪切强度较差的技术难题。通过项目研究阐明微波强化树脂/纤维界面作用的机制与物理本质，揭示微波与低能电子束协同耦合固化复合材料的作用机制与规律，并获取相应的强化效果评价方法，明确微波与低能电子束耦合作用工艺参数对构件性能影响关系，建立高强度大型复合材料构件低成本制造新方法与工艺基础。项目研究工作有助于提升我国树脂基复合材料成型制造水平，为大型复合材料构件提供具有自主知识产权的先进成型制造方法与理论。

英文摘要： With the increasing of the size of composites structure parts for industrial use, the autoclave process for composites is becoming more and more difficulty to control, and the cost is increasing rapidly, which blocked the further use of composites in industry area. The manufacture process of Electron Beam (EB) curing composites is much simple than autoclave process, and the combination property of composites cured by EB is better than that cured by autoclave. The EB curing technology is one of the promising out-clave process for low cost composites manufacture.But the lower interlayer shear strength (ILSS) is the main cause to block the wide use of composites cured by EB in industry products.In this project,a novel resolvent of interface enhancing is proposed to overcome the low ILSS of the composites cured by EB.Because the resin molecules would vibrate and rub with very high frequency because of the microwave, which results in high temperature around the fibres and intense interfunction between the resin molecules and the surface of fibre, finally the interface function between resin and fibres is enhanced by microwave.In this project,the enhancing mechnism of resin/fibre interface by microwave would be investigated; The coupling mechnism and rule of microwave and loe energy EB would be researched, and evalua
