    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. The apparatus also includes a memory configured to store the design for use by an Automated Fiber Placement (AFP) machine constructing the part.

    Abstract: A method and apparatus for forming a number of filler members. The apparatus comprises a surface model generator and an analyzer. The surface model generator generates a first surface model of a surface and a second surface model of a flexible surface. The surface and the flexible surface are to be mated to form a mated surface and a mated flexible surface. The analyzer performs a structural analysis using the first surface model and the second surface model to identify a predicted final shape of the mated flexible surface. The predicted final shape of the mated flexible surface is used to form the number of filler members to fill a number of spaces between the mated surface and the mated flexible surface.

    Abstract: A method and apparatus for ply blending. A desired thickness and a desired stiffness distribution for a composite structure are received. A model of the composite structure is split into a plurality of panels. Lamination parameters and a quantity of plies for each panel of the plurality of panels are determined using the desired thickness and the desired stiffness distribution for the composite structure. Ply shapes for each ply of the plurality of panels are determined using an objective function. A fiber angle is determined for each ply of the plurality of panels. Each ply of a first half of a panel of the plurality of panels has a different fiber angle value than each other ply of the first half of the panel.

    Abstract: Provided are assemblies, each including a first structure having a uniform coefficient of thermal expansion (CTE) and a second composite structure having a variable CTE. Also provided are methods of forming such assemblies. The second structure has overlap, transition, and baseline regions. The overlap region directly interfaces the first structure and has a CTE comparable to that of the first structure. The baseline region is away from the first structure and has a different CTE. Each of these CTEs may be uniform in its respective region. The transition region may interconnect the baseline and overlap regions and may have gradual CTE change from one end to the other. The CTE variation with the second composite structure may be achieved by changing fiber angles in at least one ply extending through all three regions. For example, any of the plies may be subjected to fiber steering.
