低成本非热压罐复合材料飞艇吊舱设计、分析、制造和试验
Design, Analysis, Fabrication, and Test for Low?Cost and Out?of?Autoclave Composite Airship Gondolas
摘要
Abstract
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 4593με;its maximum compressive strain is 3680με;and its maximum shear strain is 4884με. 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.关键词
