VACUUM MOLDING
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:
- Position COMFIL® on an open-faced mould.
- Place a vacuum bag over the COMFIL® and seal the material to the mould.
- Remove the air from the bag, sandwiching the COMFIL® between the bag and the mould.
- Heat mould to achieve material temperature of app. 25-50 degree C over the melting temperature of the matrix material.
- Cool the part to below 50-100 degree C.
- Similar to vacuum bagging for epoxy prepregs.
