本文提出了一种通过自动计数具有代表性截面的数字化显微图像中单位面积纤维端头数来确定连续纤维复合材料中纤维体积分数的方法。由于纤维计数是数字变量，该方法的准确性基本上是独立的显微镜焦点和试样表面制备的小变化。除了产生平均数据外，该方法还能够构建从最精细的可能尺度到全尺寸组件的体积分数变化曲线。结果与酸消化试验所得值一致。
A method for determining the fiber volume fraction in continuous fiber composites by automatically counting the fiber ends per unit area in digitized microscope images of representative cross sections has been developed. Since fiber counts are digital variables, the accuracy of the method is essentially independent of small variations in microscope focus and specimen surface preparation. In addition to producing averaged data, the method enables the construction of volume fraction variation profiles ranging from the finest possible scales up to full size components. Results are in agreement with values obtained by acid digestion tests.
