The method of the present invention for producing a shaped film includes a step of arranging a thermoplastic resin film to divide a space into a first space located on one surface side of the film, and a second space located on the other surface side, a step of heating the thermoplastic resin film, a step of curving the thermoplastic resin film in one space by using a difference in pressure between the first space and the second space, a step of stopping the curving step of the thermoplastic resin film in a state where at least a convex curved surface of both surfaces of the film is exposed into the space, and a step of cooling the curved film.

A system includes a curing assembly for low temperature curing and residual stress relief of material substrates. The curing assembly includes a first exposure chamber configured to expose the material substrate to UV radiation, and a second exposure chamber configured to expose the material substrate to Gamma radiation. In some embodiments, a mixing apparatus may mix nano-filler particles into the material substrate prior to exposure to Gamma radiation. The cure assembly may also include a control system for determining exposure dosages and exposure times based at least in part, on the material properties of the material substrate.

The invention generally relates to shape memory films that are tri-functionally crosslinked and that comprise multiple, non-terminal, phenylethynyl moieties. In addition, the present invention relates methods of fabricating such films. Due to the improved properties of such SMPs, the SMP designer can program in to the SMP thermomechanical property enhancements that make the SMP suitable, among other things, for advanced sensors, high temperature actuators, responder matrix materials and heat responsive packaging.
