The Virtual Manufacturing Solutionfor Liquid Composite Molding PAM-RTM

PAM-RTM is a unique simulation software which covers a wide range of manufacturing processes based on liquid composite molding. This includes Resin Transfer Molding (RTM), Vacuum Assisted RTM (VARTM), and Vacuum Assisted Resin Infusion (VARI).PAM-RTM accelerates time to market by providing user with a rapid decision-making solution for preliminary design, refined calculations for process and mold optimization, as well as final design verification. PAM-RTM helps engineers minimize the risk of producing defective parts by mastering all parameters of the manufacturing process. Resorting to simulation, engineers leverage the benefits of producing high performance composite parts.

RTM simulation solution

PAM-RTM is an innovative and easy-to-use 3D simulation package which optimizes the mold design and RTM process parameters:

Visualization: Visualizing the flow front in the mold cavity helps prevent filling problems such as dry spots. Molding parameters: PAM-RTM optimizes parameters that directly impacts the pressure distribution during the mold filling such as injection pressure, flow rate, molding temperature, closure forces, and the position of injection gates and vents. It also predicts the curing evolution inside the mold.
COMPOSITES & PLASTICS

PAM-RTM offers a great range of validated processes and allows to determine the best combination of resins and fibers

With PAM-RTM, users can simulate various types of resins such as epoxy, polyester, vinylester, phenolics… Injection simulation takes into consideration the deformation information resulting from preforming simulation (direct import from PAM-FORM, PAM-QUIKFORM, Composites Part Design Dassault Systèmes, FiberSim).Thermal issues aremastered by controllingprocess parameters:Pre-heating of the mold, 3D heatconduction inside the mold, SourceTerm, Contact Resistance. Users can define their own viscosityand curing functions, which enables themto simulate new resins. Curing modelingduring and after filling is based onKamal Sourour model.
