复合材料铺层方向制造符合性验证方法研究

Research on Verification Method of Manufacturing Conformance in the Layering Direction of Composite Materials

近几年来,随着复合材料工艺的普遍应用,复合材料制造符合性问题日益凸显,影响航空装备质量,特别是国产大飞机制造符合性问题,逐步引起用户及主制造商重视。一旦复合材料制造过程得不到有效控制,出现工艺过程参数或结果与规定的不相符,对产品质量将产生较大影响。本文将结合以往复合材料制造过程中出现的质量问题,针对复合材料铺层方向错误质量问题开展调查分析,研究其制造符合性的验证方法,以便准确识别故障产品范围,分析根本原因并制定改进措施,控制质量成本损失。

In the recent years,with the widespread application of composite technology,the problem of composite material manufacturing conformity has become increasingly prominent,which affects the quality of aviation equipment,especially the problem of domestic large aircraft manufacturing conformity,and gradually attracts the attention of users and main manufactures.Once the composite material manufacturing process is not effectively controlled,the process parameters or results are inconsistent with the regulations,which will have a greater impact on product quality.This paper will combine the quality problems in the past composite manufacturing process,analyze the quality problem of the wrong direction of the composite material layup,and study the verification method of its manufacturing conformance,in order to accurately identify the scope of the fault product,analyze the root cause and make the corrective action,control the quality cost loss.
