  • System and methods of generating a computer model of composite component
    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.
