Abstract
Systems and methods are provided for composite part design. One embodiment is a method of creating a library of sublaminates used in optimizing fiber orientations of a multi-layer composite part subdivided along its depth into panels that each comprise a fraction of the area of the composite part. The method includes creating sublaminates that each comprise consecutively stacked layers having a unique sequence of fiber orientations, checking the sublaminates for compliance with stacking sequence rules that constrain how fiber orientations are sequenced, and removing sublaminates that do not comply with the stacking sequence rules. The method further includes generating new sublaminates that each include an additional layer, by, for each of multiple fiber orientations: selecting a sublaminate that was not remove, and generating a new sublaminate by appending an additional layer having the fiber orientation to the selected sublaminate.
