碳纤维加筋板的超声相控阵C扫描检测可靠性研究
Reliability of Ultrasonic Phased Array C-scan Testing for Carbon Fiber Composite Stiffened Panels
摘要
Abstract
Carbon fiber composite stiffened panels have been widely used in modern aircraft.Ultrasonic phased array C-scan technology is one of the effective methods for this laminated structure in-service.In practice,results for the same damage of multi-crystal phased array C-scan may be inconsistent with dif-ferent detecting directions.However,this phenomenon does not occur by the conventional single crystal C-scan testing.This paper analyses these inconsistencies from surface curvature and defect characteris-tics and presents recommendations to avoid the occurrence of these uncertainties.关键词
