Fibersim Fiber Placement Interface

Providing a Seamless Link between the 3D CAD Model and the Software that Programs Fiber Placement Machines

Fiber placement machines combine the advantages of filament winding, contour tape laying, and computer control to automate the production of complex composite parts that conventionally require extensive hand layup. Fiber placement machines enhance the quality, rate and repeatability of composite part production, but creating the data to drive these machines has traditionally been tedious and error-prone.

With the Fiber Placement Interface module in the Fibersim portfolio, engineers can automatically generate fiber placement data files within their CAD software systems directly from the 3D model of a composite part. These files accurately represent part layup surfaces, ply definitions, ply orientation information and the unique fiber placement entities to significantly increase engineering productivity, eliminate errors, and make it easy to accommodate changes and optimize designs.

The Fiber Placement Interface module enables engineers to import path planning post-processing data, including course centerlines and boundary information. The module enables users to validate that the manufactured part meets design requirements by allowing them to review the imported post-processing manufacturability data, including fiber angle deviation, radius of curvature, roller height and collision avoidance angle. The ability to review for manufacturability allows for design changes that maximize production rate, part performance and cost.

Key Capabilities and Benefits

The Fiber Placement Interface helps engineers:

  • Quickly translate the composite part design and layup process definition to native path planning solution formats, including:
    • Surfaces – tool and intermediate layup
    • Plies – boundaries, material, orientation and start point
    • Machine positioning/alignment – using shaft, frame, and multipoint alignment methods
    • Processes – feed rate, temperature, pressure, coverage and tow tension
  • Reduce the risk of errors by maintaining the digital thread between design and manufacturing
  • Increases machine uptime by creating design features that minimize stoppages
  • Maximize production rate by ensuring that the design is capable of being manufactured
