Abstract
Systems and methods are provided for composite part design. One embodiment is an apparatus that designs a composite part. The apparatus includes a controller configured to generate a design for the part. The controller subdivides the part into blocks that each comprise a contiguous stack of layers within the part, identifies rules that constrain how layers that have different fiber orientations are stacked within the part, generates a guide for a block that prescribes a fiber orientation for each layer of the block, and identifies sublaminates comprising that are compatible with the guide for the block. The controller subdivides the part into panels, and selects one of the compatible sublaminates for one of the panels of the block, based on compatible sublaminates for neighboring panels.
