Product information
PAM - RTM can model a large number of processes, including:
- Plastic infusion process in the mold
- Vacuum process
- RTM compressed resin transfer process
- RTM high pressure plastic transfer process
- And many other processes
This module can predict the plastic transfer within the mold which may include added materials (such as metal, wood, foam).
- Typically the simulation results have been published:
- Fill time
- Risk of surface pitting or yarn displacement
- Material flow velocity
- Pressure is applied to the mold
- Pitting level
- Curing time
- Curing temperature and process
With PAM - RTM, manufacturing defects in the RTM process are eliminated and product quality improved during product development, before any tools were cut thanks to optimization of parameters. after:
- Material injection / transfer strategy (selection of CLM process)
- Spray pressure or tibial flow rate
- Temperature cycle (tools and plastic materials)
- Spray port position, vent and vacuum port
- Traffic types and locations
- Curing cycle
Simulations can also be used later in the process to correct problems after they have been identified.
Modeling of the car's middle cylinder on the PAM-RTM
A key parameter of liquid composites simulation is the permeability of the reinforcing material. Permeability is heavily dependent on the fiber orientation, so it is important to take these fiber directions into account in the injection / transfer simulation of the material. The geometry method can be used to estimate the orientations of the fibers in the workpiece, however it is also possible to use the exact yarn directions calculated in a PAM-FORM modeling simulation.
Thanks to a unique, high-performance DMP solver, PAM-RTM is able to process a large number of models using shell or solid elements. These large models are often applicable in the wind energy industries because of the size of the large parts and in the automotive industry because of the small details that require detailed geometries.
The ability to process very small to very large models by solid elements is the only feature available in PAM-RTM. This ability to model the solid shape is essential to knowing how the plastic flows through thickness determination and risk identification for the dry areas within.
