Abstract
A method of designing a composite panel, the panel comprising a plurality of zones, each zone comprising a plurality of plies of composite material arranged in a stacking sequence, each ply in each stacking sequence having a respective orientation angle. For each orientation angle a first layout matrix is created which identifies zones in the panel which contain at least one ply with that orientation angle. A second layout matrix is also created which identifies zones in the panel which contain at least two plies with that orientation angle, and so on up to an Nth layout matrix which identifies zones in the panel which contain at least N plies with that orientation angle. The layout matrices are arranged in a plurality of candidate sequences. Selection criteria are then used to choose one or more of the candidate sequences and stacking sequences are assigned to the zones in accordance with the chosen candidate sequence(s).
