The contents of this publication include a tutorial to approximate the chirality, or twist, of fibers in a fiber reinforced ceramic matrix composite. There is a sample dataset that contains images of a SiC matrix composite with SiC reinforcement fibers. The MATLAB code performs the velocity gradient analysis and visualizes the results of this analysis. In the near future, the authors intend on publishing a paper about the derivation of the applied methods, which will be titled: "Mesoscale Characterization of Continuous Fiber Reinforced Composites Through Machine Learning: Fiber Chirality".
