摘　　要：复合材料泡沫夹层结构质量轻,具有较大的弯曲刚度和强度,是承载效率较高的结构形式。目前,部分飞机开始设计泡沫夹层结构复合材料舱门,且舱门金属接头连接区域镶嵌有大厚度实体填块。该类结构形式的零件制造工艺复杂,成形后制件的内部及表观质量不易控制,技术风险高。本文试验描述了一种大尺寸、大厚度泡沫夹层舱门零件的成形工艺设计,研究了泡沫夹层舱门零件制造过程中的关键技术,解决了制造过程中的技术质量问题。试验结果表明,符合图样要求且内部质量和表观质量合格的泡沫夹芯门部件可以通过共黏工艺制造。研究成果可推广应用到飞机机翼、舱门和扰流板等承重结构中。The composite foam sandwich structure is a structural form with high bearing efficiency,which has the characteristic of light weight,large bending stiffness and strength.At present,some aircraft begin to design composite hatch doors with foam sandwich structure,and metal joint connection area of hatch doors has solid filing blocks with large thickness.The manufacturing process of this kind of structural style is complex,the internal and apparent quality of the formed product is not easy to control and technical risk is high.This experiment describes the molding process design of a large-size and large-thickness foam sandwich door,studies the key technologies in the manufacturing process of foam sandwich door and solves the technical quality problem in the manufacturing process.The test results show that foam sandwich door parts that meet the requirements of the drawings and internal quality and apparent quality are qualified can be manufactured through co-bonding process.The research results can be popularized and applied to the load-bearing structures of aircraft wings,doors,and spoilers.
