【摘要】 本文采用高性能碳(玻璃)纤维2D增强机织物，利用增粘纺织预成型技术，开发出了适用于民用客机尾翼整体蒙皮用叠层预制件。设计了适用于树脂膜熔渗工艺(RFI—Resin Film Infusion)的模具和剪切实验用夹具，对增粘叠层预制件压缩性能、渗透性能及RFI工艺一维树脂流动模型进行了理论和试验研究，研制出适合本课题用高性能环氧树脂膜，通过优化设计树脂膜熔渗工艺(RFI)，制造了T型整体壁板蒙皮复合材料制件。 树脂传递模塑(RTM—Resin Transfer Molding)工艺存在加工尺寸的技术限制，热压罐袋压成型工艺(BMPA—Bag Molding Process for Autoclave)一般仅能有效加工单向带和2D预浸料，树脂膜熔渗工艺(RFI)突破了加工尺寸和预制件型式的限制，其工艺过程简单、成型压力低、制造成本低，适宜制造大型板类、壳类复合材料制件，在航空和船舶航空、船舶及建筑等行业具有广泛的应用前途。 本文对增粘缝纫叠层预制件(增粘处理方法、增粘处理工艺)和高性能环氧树脂膜(树脂膜配方、树脂膜加工工艺和树脂膜性能测试方法)的研制过程、树脂膜融渗(RFI)工艺设计方法、RFI一维流动模型、RFI工艺模具和剪切实验用夹具的设计研究进行了详细地分析论述，其技术工艺和理论成果可直接应用制造领域。 根据技术性能的要求，对T型整体壁板蒙皮制件进行树脂浸润质量检测和剪切屈曲实验，测试结果表明T型整体壁板孔隙含量较低，其临界屈曲强度、破坏强度及破坏模式均达到设计要求。更多还原

【Abstract】 In this dissertation, tackified laminate performs manufactured by tackified textile performing technology and high performance carbon fiber (glass fiber) 2D woven fabric have been developed, it will be used on tail integrated panel of civil plane. The consolidation and permeability characterization of tackified laminate performs, and one dimensional RFI resin flow modeling was fully discussed with test methods. Toolings suitable for the Resin Film Infusion (RFI) process and shear test rig have been designed. By developing epoxy resin film and optimizing technical data of resin film infusion (RFI), several T integrated panels were successfully produced.There are some technical limitations in manufacturing super size composites with Resin Transfer Molding Process (RTM), generally speaking Bag Molding Process for Autoclave can efficiently process unidirectional and 2D prepreg, but Resin Film Infusion process can be used to manufacture panel and shell with ultra size. It has following advantages such as simple technological process, low pressure and cost. In the near future, RFI process will be extensively utilized in aviation, shipping and building industry.This paper studies the manufacturing process of tackified stitching laminate performs (tackified method and technology) and epoxy resin film with high property ( formulation, manufacturing technology and performance test methods of resin film), and analyses the design method of Resin film infusion technology, RFI one dimensional resin flow modeling , RFI toolings and test rig, these technical data and theoretical results can be transferred to the industry fields.The resin infusion test results show the T integrated panels has very low void content, shear buckling test demonstrates that the critical bucking load, failure load and failure mode of T integrated panels (stitched and unstitched) are over the technical requirements.更多还原
