RTM is the process designed for the impregnation of multiple reinforcement layers using pressure (and in some cases vacuum) in a closed mold.
The resin system is injected under pressure, which is then maintained throughout the polymerization process.
High Pressure RTM (or Fast RTM) is based on the same principle, but unlike standard RTM, this process requires significantly higher mixing, injection and curing pressures (typically 15 bars or greater).
Main benefits :
- Fast RTM process meets the automotive industry’s requirements with regard to automation and cycle time in mass production •
- High quality composites
- Good surface finish
- Closed process
- Design flexibility
