民用航空含Ω型长桁复合材料加筋壁板制造技术研究

含Ω型长桁的复合材料加筋壁板由于其结构上的优势,在民用大飞机上被越来越多地采用。然而,此种类型的加筋壁板在共固化成型过程中存在Ω型长桁如何加压的问题,特别是在有严格的适航符合性审查要求的民用航空产品制造领域,进一步提高了制造难度。经过多次试验,最终采用薄壁橡胶气囊成型法制造出符合设计要求和适航要求的含Ω型长桁加筋壁板。

Study on Manufacturing Technology of Ω Type Stiffened Panel of Civil Aviation

Ω type composites stiffened panel has been widely used in large civil aircraft due to its structural advantage.But some difficulties exist in how to pressurize these Ω type stiffened panels during the co-curing process.Especially there are strict airworthiness compliance review requirements in the field of civil aviation products manufacturing,thereby further increasing the manufacturing difficulty.After a number of tests,the group decided to adopt thin-walled rubber balloon forming method to manufacture the Ω type stiffened panel in order to meet design requirements and airworthiness requirements finally.
