摘　　要：Out-of-autoclave(OoA) processing has the advantages of low cost,light weight and environmental protection,and has become a hot spot in the field of composite materials worldwide. This paper investigates the application of OoA processing in the gondola of the AS700 civil manned airship. The production cost of gondolas is reduced by selecting low cost materials such as glass fiber,PVC foam and OoA processing. The porosity of parts is reduced and controlled at about 2% by optimizing the edge breathing of prepreg during curing. The maximum tensile strain of the glass fiber is 4 593 με;its maximum compressive strain is 3 680 με;and its maximum shear strain is4 884 με. The maximum Von Mises stress of the foam is 0.70 MPa. These settings all meet the margin requirement of safety. Finally,the ultimate load test of the gondola is carried out to verify the safety of the gondola structure. Our study presents critical parameters for the gondola design,including load,structure,strength,and manufacturing process test,and provides certain references for the design of similar products.非热压罐成型(Out-of-autoclave processing,OoA)具有成本低、质量轻和绿色环保等优点,已成为世界复合材料研究领域的热点。本文介绍了OoA成型工艺在载人飞艇AS700吊舱上的应用。通过选择低成本材料(如玻璃纤维、PVC泡沫)和OoA成型工艺降低了吊舱的生产成本,通过优化固化过程中预浸料的边缘呼吸降低了零件孔隙率,使吊舱零件孔隙率控制在2%左右。吊舱结构中玻璃纤维的最大拉伸应变为4 593με,最大压缩应变为3 680με,最大剪切应变为4 884με,泡沫最大Von Mises应力为0.70 MPa,满足安全裕度要求。同时,开展了吊舱极限载荷试验,验证了吊舱结构的安全性。本文对载人飞艇吊舱载荷、结构、强度、制造工艺和试验等做了介绍,可为同类产品设计提供一定的借鉴。
