1. A computer-aided method of obtaining a preliminary ply model of a composite component to be used in the manufacture of industrial parts by stacking and joining a plurality of plies of composite materials comprising the following steps:

  • a) obtaining from stress calculations a ply stacking sequence for the composite component subdivided into panels;

    b) based on said ply stacking sequence, automatically generating a first preliminary ply model identifying the panels covered by each ply by means of bidimensional tables;

    c) optimizing said first preliminary ply model merging plies for obtaining larger plies and/or separating plies for obtaining plies forming a closed contour by means of a graphic tool that allows automatic;

    c1) detection of possible ply mergers between plies covering contiguous zones; and

    c2) separating plies into layers, obtaining single layers forming a closed contour, and assigning a unique number to that layer;

    d) performing the plies drop-off distribution by means of a tool that allows carrying out said distribution automatically according to a predetermined staggering rule and the graphical visualization of said distribution;

    e) obtaining an output table containing the data required for representing the preliminary ply model in a CAD program and/or representing a sectional view of any of those areas were there is a change in the stacking sequence.
