COMPUTER IMPLEMENTED METHOD TO OBTAIN THE ORIENTATIONS OF FIBRES INSIDE COMPOSITE MATERIALS USING COMPUTED TOMOGRAPHY SCAN

摘要

Computer implemented method to obtain the orientations of fibres inside composite materials using computed tomography scan, comprising: - Obtaining tomography scan images of different cross sections of the composite material; - Converting said images into a set of points, each point representing a pixel of the image with a grey-scale value and 3D coordinates; - Extracting the pixels corresponding to the fibre material by using a threshold gray-scale value; - Clustering the pixels of the fibre material corresponding to the same cross-section in individual fibres according to distance criteria between pixels; - Assembling the individual fibres located in different cross-sections and corresponding to the same single fibre by estimating the position of the centroid of each individual fibre in an immediate cross-section; - Obtaining the interpolation line of each cloud of pixels belonging to a single fibre and, from said interpolation line, obtaining the orientation of each single fibre.
