摘要
复合材料在通用飞机中使用率高,多种机型高达90%以上,因此复合材料的缺陷会严重影响飞行安全性。本文设计了一种基于红外成像检测技术的飞机复合材料的缺陷精准检测方法及原型无损检测系统。无损检测系统由数据采集系统、信号源组、红外热像仪组、红外图像处理重构系统等组成,可实现对飞机复合材料结构中缺陷类型及平面尺寸的辨识和深度的准确定位。搭建了光激励型红外成像飞机复合材料检测系统,对复合材料进行了不同温度的检测试验并给出了研究结果。此研究结果将扩展国内红外无损检测技术的使用场景,成果转化后将有利于解决飞机在通航中维修保养问题。
Composite materials are widely used in general aircraft,with usage rates exceeding 90%in various types of aircrafts.Therefore,defects in composite materials can severely affect flight safety.This paper designs an accurate defect detection method for aircraft composite materials based on infrared imaging detection technology,as well as a prototype non-destructive testing system.The non-destructive testing system consists of a data acquisition system,signal source group,infrared thermal imager group,and infrared image processing reconstruction system,which can identify the type and planar size of defects in the aircraft composite material structure and accurately locate the depth.A light-excited infrared imaging detection system for aircraft composite materials was built,and detection experiments were conducted on composite materials at different temperatures,with research results provided.These research results will expand the application scenarios of domestic infrared non-destructive testing technology,and the commercialization of research findings will be beneficial in solving maintenance and repair issues during the general aviation of aircraft.
