  • Patent number: 10062202
    Abstract: A method for generating a computer model of a composite component includes generating a surface mesh based on a ply drop region and a ply curved surface and generating node data including a plurality of node points relative to the ply drop region. The method also includes receiving composite data relating to a plurality of composite plies and generating a three dimensional model based on the composite data. The method further includes receiving layup table information and applying the node data, based on the layup table information, to generate a curve through a center of the surface mesh to define a plurality of element sets. The method also includes receiving composite draping data and determining, based on the draping data, where each element set intersects the three dimensional model. The method also includes analyzing an angle deviation of the plies based on the intersection of the element sets.

  • Patent number: 9524356
    Abstract: A computer-implemented method for generating a computer model of a composite component includes offsetting a projected ply boundary curve outwardly along a base surface by a ply drop distance to define an offset ply boundary curve. Moreover, the method includes defining a ply region of the base surface, wherein ply region includes an area of the base surface that is interior the ply boundary curve. A ply drop region is defined, wherein the ply drop region includes another area of the base surface that is exterior the ply boundary curve and interior the offset ply boundary curve. The method includes generating a point cloud relative to the base surface, wherein the point cloud comprises a plurality of reference points and generating a ply surface using each reference point of the point cloud to facilitate generating a manufacturing lay-up sequence for the plurality of plies.

  • Publication number: 20150370923
    Abstract: A computer-implemented method for generating a computer model of a composite component includes offsetting a projected ply curved surface outwardly along a base surface to define an offset ply curved surface. The method also includes defining a ply drop region of the base surface, the ply drop region includes another area of the base surface that is exterior to a ply curved surface and interior to an offset ply curved surface. A surface mesh is generated based on the ply drop region and the ply curved surface. The method includes generating a node data comprising a plurality of node points relative to the ply drop regions. Moreover, the method includes applying a curved function to the plurality of node points to facilitate forming a smoothed node data across the ply drop region. A ply mesh is generated using the smoothed node data and the surface mesh.
