Abstract
A method includes obtaining an image of a composite material part, each pixel of the image representing material density at a point of the part represented by that pixel; extracting from the image, for at least one fiber element of the part, a line that is representative of that element along its length; for each extracted line extending this line in width at reference points in compliance with the width of the fiber element, this extension resulting, for each reference point, in extended points; and associating an orientation with each extended point associated with a reference point, which orientation is parallel to the direction of the line at that reference point; evaluating, for a plurality of extended points, a mean orientation of the fiber elements at those points; and determining, for a plurality of orientations, a proportion of elements having those orientations from among the evaluate mean orientations.
