随着复合材料在民航飞机中的应用日益增多,其结构损伤情况也呈现多样化,包括分层、树脂瑕疵和蜂窝积水等特有内部损伤,对此本文提出了多种实用的检查方法,如敲击、超声波、X-射线和红外成像等。 With the increasing application of composite materials in civil aviation aircraft, structural damage has also been diversified, including specific internal damage such as delamination, resin defects and honeycomb dewatering. In this paper, a variety of practical inspection methods are proposed, such as Percussion, ultrasound, X-ray and infrared imaging.
