Description

Wrightlon® 3800 is a white matte finished Polyethylene Teraphthalate (PET) release film used as a barrier between tool surfaces and composite materials applied using automated tape layup and automated fiber placement equipment. The use of Wrightlon® 3800 allows the composite to be transferred to final cure tooling. In typical application Wrightlon® 3800 may remain with the composite through heat debulk cycles or forming operations. Wrightlon® 3800 should be removed prior to final cure or it will bond with the structure.

Benefits

• Economical film greatly reduces costs in fiber placement, compaction and forming processes.
• Flat film can be applied quickly and without wrinkles over simple tool shapes.
• High strength means film remains stable on tool under force of fiber placement lay-up head.
