The presented method allows measuring the braid angle, taking into account the magnitude of its deviation from the specified value, which makes it possible to assess the braid angle unevenness in the structure of the textile preform. The method was developed using image analysis tools and fast Fourier transform, the mathematical apparatus of which allow investigating the frequency characteristics of digital images of braided structures and measuring the yarns and threads orientation in a braided structure, taking into account their unevenness. The accuracy of calculations has been confirmed by the results of the analysis of images of braided structures with specified parameters, for which the braid angle and the magnitude of its deviation from the specified value have been measured. A conclusion about the efficiency of using the developed method for accurate measurement of the braid angle and the magnitude of its deviation from the specified value in braided preforms has been made.
