摘　　要：研究了一种新型轻质碳纤维复合材料整体桁架结构形式及其成型方法,介绍了采用水溶性芯模技术并使用真空袋热压罐成型方式制备轻型田字形碳纤维复合材料整体桁架结构件的工艺路线和产品成型效果。结果表明:采用水溶性芯模制备轻型复合材料整体桁架结构质量良好,各项技术指标满足设计使用要求。为整体框架的研制提供一种崭新的思路和方法的同时,极大地缩短了框架结构的研制工艺流程,提高了其整体性能。The paper studied a new type of lightweight carbon fiber composite truss structures and its formingmethod, and introduced the process route and product forming effect of the light shape of carbon fiber composite trussstructure using the water soluble core technology and the vacuum bag autoclave molding. The results show that： thequality of light whole composite truss structure prepared by water soluble core mold was well, and various technicalindicators meet the design requirements. It provided a new thought and method for the development of whole trussstructure, which can greatly shorten the development process and improve the overall performance.
