Thermoset Materials

User interface parameter updates for thermoset materials improve usability and solver updates improve the accuracy of Fill, Pack, and Warp simulations.

Simulations account for the orientation effects of fiber-filled thermoset materials which improve the solution accuracy.

The table lists the user interface parameters that are renamed, and one new parameter that is added.

Thermoset Material Ejection Criteria
  • Curing-based directs the solver to continue the curing simulation until the material reaches the specified target curing level, eliminating the guesswork of determining the curing time.
  • Time-based sets a specific curing time for the solver to complete the thermoset curing simulation. After you run the simulation, you can review the results to determine the percentage of curing achieved across your model and adjust the curing time to either shorten or extend the process.
Ejection Conversion % Material’s Target Curing Level at Ejection sets the percentage of curing at which the thermoset material reaches its gelation point—where its viscosity becomes infinite, and it loses the ability to flow. Curing beyond this level is not beneficial and only adds to the manufacturing cycle time. This characteristic is an intrinsic property of the material determined through characterization, typically provided by the material manufacturer.
  New parameter: Volume % Above Target Curing Level at Ejection sets a threshold volume percentage that determines the ejection point. The default setting is 90%, meaning the part is ejected once 90% of the plastic volume reaches the target curing level.
