摘要: 利用CCD 摄像机和专用A/ D 板采集的碳纤维织物增强的复合材料层合板截面图像检测碳纤维机织物增强复合材料的纤维体积含量。按照测定纤维体积含量的原理, 设计了几何法和阀值法的测试步骤。用Photo-shop 软件对所采集的图像进行数据处理分析, 获得了层合板的纤维体积含量值。对比分析表明, 检测结果与所采用复合材料的纤维体积含量标准值相符合。可以认为利用界面图像测定纤维体积含量的方法是可行的。

Abstract: The methods for determining the fiber volume fraction in carbon fabric reinforced composite laminateswere developed by using the processing and analyzing techniques of section images of laminates , which are sampledby the use of CCD camera and A/ D device. Special measuring step s were designed according to the principles of determining the fiber volume f raction , using the geomet rical method and threshold method. The captured images weremanipulated and analyzed using Photoshop sof tware. The result s are in agreement with the values offered by thecomposites maker. Therefore the methods are considered feasible.
