摘要/Abstract

摘要： 采用X射线断层CT成像检测、X射线螺旋CT成像检测和X射线锥束CT成像检测三种X射线CT成像检测方法对预制机械加工模拟分层缺陷的碳纤维树脂基复合材料进行检测,从检测速度、检测图像质量、缺陷分辨率三个方面比较这三种X射线CT成像检测方法。结果表明,X射线锥束CT成像检测方法在对复合材料内部分层缺陷的检测中具有检测效率最高,检测图像质量最好以及缺陷尺寸测量误差最小的优点,为复合材料内部其他缺陷检测方法的选择提供借鉴意义。

Abstract: Three kinds of X-ray CT imaging detection methods including X-ray tomography CT imaging detection method, X-ray spiral CT imaging detection method and X-ray cone beam CT imaging detection method were used to detect carbon fiber matrix composites with prefabricated mechanical processing simulated delamination defects. These X-ray CT imaging detection methods are compared from three aspects, i.e., detection speed, image quality and defect resolution. The results show that the detection method of X-ray cone beam CT imaging has the highest detection efficiency, the best image quality and the smallest defect size measurement error in the detection of delamination defects in composite materials. It provides a reference for the selection of other defects in composite materials.

Key words: X-ray CT imaging detection, composite material, selection of detection methods
