Description

Permagrip is bonded around the mould periphery in the excess part area. Full skin plies are extended over the Permagrip and become anchored in place during autoclave processing. This method of fabrication will greatly inhibit or eliminate core movement.

Benefits

• Reduce or eliminate core movement
• Avoid costly rejections
• Avoid scrap or expensive rework or scrap

Application

Preparation for bonding to the mould:
Abrade and solvent wipe the bond surface of the mould and the Permagrip. All mould release and oxidation must be removed from these surfaces.
Bonding (option 1):
