Provided is a mold release film capable of transferring a concave-convex structure to the surface of an adhesive film.

Systems and methods are provided for adjustable tooling. One embodiment is a method that includes laying up a laminate of fiber reinforced material onto a continuous surface that has a convex profile and that comprises a first contoured surface of a fixed mold of a composite layup tool and a second contoured surface of a movable mold of the composite layup tool. The method also includes displacing the movable mold in a direction that is at least partially towards the fixed mold, breaking the continuous surface and releasing the laminate from the composite layup tool.

To provide a release film not to contaminate a mold or a molded article. The present invention provides a release film comprising a base layer formed of an easily moldable polyethylene terephthalate resin and surface layers laminated on two faces of the base layer and formed of a fluororesin. The present invention also provides a method of manufacturing a release film. The method comprises an applying step of applying a fluororesin composition onto two faces of a base layer formed of an easily moldable polyethylene terephthalate resin and, after the applying step, a curing step of curing the fluororesin composition. By molding with the release film, contamination of a mold or a molded article is prevented. The release film can be used in molding multiple times.
