全碳纤维复合材料飞机零件无损检测验收标准探析

Acceptance Criteria Analysis of Carbon Fiber Composite Aircraft Parts

通过对全碳纤维复合材料飞机零件的验收实践、被检出缺陷零件的试验、国内外相关标准的比较,分析了单个缺陷的损伤容限;同一零件不同部位损伤容限区别;多个缺陷的计算方法;多个缺陷区域间距离极限的计算公式;目视检测和采用多种无损检测方法检测的必要性;完善了适合本公司全碳纤维复合材料飞机零件的无损检测验收的标准。

Through practical acceptance of full carbon fiber composite aircraft parts in bulk, The test is detected defective parts, Comparison of domestic and foreign standards, Damage tolerance analysis of a single defect; The same parts in different parts of the difference between damage tolerance： Calculation inultiple defects： Maxirnum distance between the plurality of defect regions formula; The necessity of using a variety of detection and non-destructive testing methods to detect visual; The company improves the fit full carbon fiber composite aircraft parts batch acceptance criteria,
