Combination of PU measurement tool system with CAE Simulation for accurate PU foaming prediction

Polyurethane foam is widely used in automotive industry; however; it is very challenging to assess the quality of final product. Here we will demonstrate how it is possible to combine a measurement tool system (FOMAT) with Moldex3D to finetune the material parameters in order to achieve a better material model and final product.

Moldex3D has the ability to simulate the foaming and filling process of foam materials and predict properties of final products. To do so, an accurately parameterized material model is very crucial for a successful simulation.

In a study done by Moldex3D researchers, it has been illustrated how they can characterize PU materials using a universal foam qualification system, FOAMA, together with Moldex3D simulations. FOMAT is able to measure physical properties during foam formation such as foam rise height, reaction temperature, rise pressure, curing and viscosity.

By comparing the results from Moldex3D and FOAMAT, they are able to optimize the material models and their parametrization. The image above shows the comparison of the final experimental and simulation results of the height of an example mold and it shows a good comparison between the two.

Lastly, the measured material parameters can be used in Moldex3D simulation module to simulate a part with PU.
