Vacuum moulding is used to make single and/or large composite parts with a one-sided tool and a vacuum bag to form the component. This process is similar to vacuum bagging for thermoset composites. Silicone reusable membranes can be used for some matrix materials.
Key Processing Points:
Rovings are pulled from a package through a tensioning device and into an infrared or convection oven to heat the COMFIL® min. 25 degree C over the melting temperature of the matrix material.
A guide-eye positions the molten COMFIL® rovings onto the rotating mandrel, forming the composite.
COMFIL® efficiently reinforces plastic liners composed of the same thermoplastic.
