Computer-aided method of obtaining a ply model of a composite component
First Claim
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 such as carbon fibres, comprising the following steps a) obtaining from stress calculations a ply stacking sequence for the composite component subdivided into panels;
- b) automatically generating a stacking table containing the ply sequence for each different zone of the composite component, each zone being defined by its ply sequence;
c) automatically generating a grid table containing identification data of the zone corresponding to each panel;
d) optimising said stacking table by means of a graphic tool that allows the automatic detection of possible ply mergers for obtaining larger layers and/or possible ply separations for obtaining single layers forming a closed contour;
e) 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;
f) obtaining an output table containing the data required for representing the ply model in a CAD program and/or representing a sectional view of any of those areas were there is change in the stacking sequence.
