摘　　要：研究了基于CT扫描成像的纤维预制体内部质量检测方法。通过工业micro-CT成像得到预制体的三维模型,通过对比阈值分割和梯度分割的技术,阈值分割的方法效果优于梯度分割的方法,实现了预制体内部不同方向纱线的分割。基于CT软件的后处理模块开展纤维体积分数计算,可以准确评估纤维体积分数。提出了一种可靠、高效的纤维预制体内部质量检测方法,对三维编织复合材料的质量控制、结构设计和生产制造的进一步研究提供借鉴和参考。The method of inspecting the internal quality of fibre preforms based on CT scanning imaging is investigated.A 3D model of the preform is obtained by industrial micro-CT imaging,and the segmentation of yarns in different directions inside the preform is achieved by comparing threshold segmentation and gradient segmentation.The fibre volume fraction is calculated with the aid of the post-processing module of the CT software and the fibre volume fraction can be accurately assessed.A reliable and efficient method to detect the internal quality of fibre preforms is presented,which provides references for further research on quality control,structural design and manufacturing of 3D textile composites.
