Adding Laminates

You can add new laminates, either in the session or outside 3DEXPERIENCE.

Notes:
  • This task is available in Composites Design, Composites Manufacturing Preparation.
  • An alternative is to use Power Copy.

    For more information, see Managing Power Copies in Generative Shape Design User's Guide.

Tip: An alternative is to use Power Copy.

  1. From the Plies Design or from the Grid Design section of the action bar, click Composites Parameters .
  2. In the Laminates tab, click Add Laminate.
  3. Optional: Edit the proposed Name and a Color.

    Tip: The number of colors is limited to 56. However, you can define more than 56 laminates, but some of them share the same color.

  4. Select an option to define the laminate.
    • Stacking Sequence
    • Thickness Law where you give the number of plies for each material for each orientation.
    • Thickness Ratio where you give the desired thickness and the physical property defined by an orientation ratio.

    At edition, you can switch between Thickness Law and Thickness Ratio.

  5. For Stacking Sequence
    1. Select a material from the Material list.
    2. Select a direction from the Orientation list.
    3. Click Add.
    4. Repeat as required.
    5. Optional: Define a type of Symmetry (None, Pivot, Non Pivot) to define only half of the stacking.

      If you select Pivot, the last layer in the list is not used to compute the symmetric layers.

    6. Select a material /orientation couple in the list, and use the arrows to reorder it.
    7. Right-click a material /orientation couple in the list to remove it or change the material or orientation.
  6. For Thickness Law
    1. Select a material to add a line in the thickness law.
    2. For each direction, use the spinner to define the number of layers.
    3. Right-click a material to remove or change it.
  7. For Thickness Ratio
    1. Enter the target Reference Thickness.
    2. Select a material to add a line in the thickness.
    3. For each direction, use the spinner to define the corresponding percentage.
    4. Verify the total Filling Ratio.

      • You cannot edit Filling Ratio, only modify the percentages below.
      • Filling Ratio must be equal or greater than 100% to reach the reference thickness.
      • Because each ply has a given thickness that depends on the material
        • Filling Ratio cannot always reach exactly 100%.
        • Because the thickness is a multiple of the ply thickness, a valid filling ratio is 100% or more.
          • If it is over 100 %, the laminate is computed, but is thicker than the target thickness.
          • If it is below 100%, the light is red. The laminate is computed, but the target thickness is not reached,

  8. Click OK to validate and revert to the Composites Parameters dialog box.
    Laminate information is listed:
    • Order
    • Name
    • Type: TL for thickness law, TR for thickness ratio, SS for stacking sequence, SS-MSS for Main Stacking Sequence.
    • Thickness
    • TL/SS
    • Use status
  9. Select a laminate, re it using the arrows, edit or remove it.

    Note: When editing a laminate marked SS-MSS (defined from a Main Stacking Sequence)
    • You can only edit the color or switch to standard stacking sequence mode. In this case, a warning is displayed and the layer data are lost.
    • A layer level and a layer name columns are added to the stacking sequence definition.

  10. Select Prevent creation of laminates out of Composites parameters to forbid the automatic creation of laminates by other commands (For example to use only laminates validated by the company).
  11. To define laminates outside 3DEXPERIENCE platform:
    1. In Export to file, click ... to select the storage location and the name of the file to which the current data are exported.
    2. Click Export.

      If a Main Stacking Sequence exists, a message warns you that it is exported as a standard stacking sequence. You are invited to export from the Main Stacking Sequence tab instead.

    3. Edit the file.
    4. In Import to file, click ... to select the storage location and the name of the file to reimport.

      Notes:
      • The laminate name of a TL/TR/SS laminate must be different from that of an existing Main Stacking Sequence laminate.
      • Any Main Stacking Sequence in the file is ignored. A warning invites you to import from the Main Stacking Sequence tab instead.

    5. Click Import.
  12. Click OK.
    The materials, orientations, and laminates definitions are stored under Composites Parameters.

    Right-click Composites Parameters to edit them or isolate materials.
