Abstract: High fiber alignment in composites made from discontinuous fibers is well known to be critical for improved tensile strength in the fiber direction. Advances in laboratory X-ray micro-computed tomography (CT) systems have enabled the three-dimensional visualization of composites at a high enough resolution to quantitatively measure fiber orientations. CT scan settings were optimized for improved image quality and important scanning considerations are discussed. Volume Graphics software was utilized to quantify carbon fiber orientations, and the results were independently validated through optical microscopy. Additionally, results of a sensitivity analysis for various software parameters and thresholding levels will be presented. This paper summarizes the methodology of a new technique for quantifying fiber orientations from high resolution CT scans and potential applications are discussed.
