Setting up a Resin Transfer Molding analysis

For an RTM or SRIM analysis, resin is forced to flow through a cavity in which reinforcing preform (also called fiber mat) is present.

The fiber-mat, or preform reinforcement is positioned in the mold, and the mold is closed and heated under pressure. The mold is then opened and the part is removed. In order to run an RTM or SRIM analysis, you must specify a preform surface on the entire part.

  1. In the Layers pane, deselect all layers except the layer containing the cavity elements.
  2. Click Select All (Geometry tab > Selection panel > Select All) to select the entire model.
  3. Click Assign (Geometry tab > Properties panel > Assign).
  4. Click New > Preform surface to assign the Preform surface property to all model elements. In the Preform Surface dialog, you can use the selected preform, edit the properties of the selected preform, or select a new preform.
  5. Select the required preform for the analysis. If you click Select, you can search the supplied database for an appropriate preform to use.
  6. Specify the required preform thickness option.
  7. Specify the required preform orientation.
  8. Click OK twice.
