Aircraft structural materials


Fluoropolymer films are used in CFRP (carbon fiber reinforced thermosetting polymer) production process as a mold release mechanism. Fluoropolymers allows parts to be removed without damage.

Release film for CFRP

Required characteristics

- Non-adhesive properties

- Mechanical properties (tensile strength, elongation)

- Flexibility

- Thermal resistance

- Chemical resistance

- Oil resistance

Daikin Solutions

The CFRP molding process requires a release film, like Daikin’s NEOFLON FEP, with excellent heat and chemical resistance to allow for easy removal of parts from the mold after thermosetting. These films perform well in both autoclave and high temperature curing processes.
