Adding Laminates

This task shows you how to add laminates used in your design

See More about Materials and Laminates for more information.

Available in Composites Engineering Design (CPE), Composites Design for Manufacturing (CPM) and Composites Braiding (CPB).

Open an empty CATPart in either Composites Design or Grid Composites Design.
  1. Click Composites Parameters  in the Parameters toolbar.
    Go to the Laminates tab to add laminates.

  2. Click Add Laminate.

  3. A default Name and Color are proposed.
    You can edit this name, and select another color from the list.
    The number of colors is limited to 56.
    You may define more than 56 laminates, but some will share the same colors.

  4. Choose how you want to define the Laminate:
    Select either Stacking sequence or Thickness law.

  5. If you have selected Stacking sequence:
    • Select a material from the Material list.
    • Select a direction from the Orientation list.
    • Click Add.
    • Repeat as necessary.
    • Define a type of Symmetry to define only half of the stacking, if applicable (None, Pivot, Non Pivot).
      If you select Pivot, the last layer in the list is not used to compute the symmetric layers.
    • Select a material/orientation couple in the list, and use the arrows to re-order it.
    • Right-click a material/orientation couple in the list to access its contextual menu.

  6. If you have selected Thickness law:
    • Select a material to add a new line in the thickness law,
    • For each direction, use the spinner to define the number of layers in that direction.
    • Right-click a material to access its contextual menu.

  7. Click OK to validate and revert to the Composites Parameters dialog box.

    or

  8. In the Laminates tab, select a laminate
    • Use the Up and Down arrows to change the order of the laminates,
    • Click Edit Laminate to edit it.
      When editing a laminate marked SS-MSS, i.e. defined from a master stacking sequence, you can only edit the color or switch to sandard stacking sequence mode.
      In this case, a warning is displayed and the layer data are lost.
    • Click Remove Laminate to remove it.

  9. Select the Prevent creation of laminates out of Composites parameters to forbid the automatic creation of laminates by other commands.
    For example, this ensures that only laminates validated by the company are used.

  10. You can also define the laminates outside of V5:
    • In Export to file, click ... to select the storage location and the name of the file to which the current data will be exported.
    • Click Export to launch the export.
      If a master stacking sequence exists, a message warns you that it will be exported as a standard stacking sequence.
      You are invited to export from the Master Stacking Sequence tab instead.
    • Edit the file.
    • In Import to file, click ... to select the storage location and the name of the file to re-import.
    • Click Import to start the import.
      The laminate name of a TL/SS laminate must be different from that of an existing master stacking sequence laminate.
      Master stacking sequences in the file are ignored. A warning invites you to import from the Master Stacking Sequence tab instead.

    The laminate definition is updated with the information retrieved from the external file.

    Both Excel and texts files are supported. laminates.txt and laminates.xls are provided in the samples directory as examples.

    Although we do not recommend it, it is possible to import the laminates from a grid definition file exported as explained in Exporting/Importing Grid Data, as this file contains both information on the grid and on the laminates. However, note that the information on the grid will not be taken into account. In particular, if you re-export the laminates obtained this way from the Composites Parameters dialog box, the information on the grid will be lost in the export file.

    The Import Laminate command is also different, as it imports laminates information specific to defined zones, given as thickness laws, without color data, while Composites Parameters imports full laminates information, with stacking defined either as thickness laws or stacking sequences.
