Methods for placing an indicia on a composite structure generally include printing the indicia on a first film surface of a coating film, with the coating film being in a partially cured state at the time the printing the indicia is performed, and positioning the coating film on a partially cured composite structure such that a second film surface of the coating film faces and is positioned against a surface of the composite structure, with the second film surface being opposite the first film surface. Finally, the coating film and the composite structure may then be co-cured. Systems for printing an indicia on a composite structure generally include the coating film, a printer configured to print the indicia on the first film surface of the coating film, a securement configured to secure the coating film during printing, and a curing device for co-curing the coating film and the composite structure.

Disclosed is a stretchable, three-dimensional tubular structure formed due to processing-induced wrinkles to result in a platform for stretchable interactive electronics. The three-dimensional tubular structure is fabricated simply by releasing a pre-stretched two-dimensional film-substrate precursor, and the resulting wrinkled surface shows a strong directional dependence that drives the tube formation.

A graphic assembly, such as a floor or road surface sign for vehicle traffic and/or pedestrian traveled areas, is provided. The graphic assembly can include a polymeric substrate layer fixed to a fabric layer that is positioned between the polymeric substrate layer and an adhesive layer. Further, the graphic assembly can comprise a top surface that includes a plurality of surface enhancement particles embedded within a particle receptive layer that is adjacent to the polymeric substrate layer. The plurality of surface enhancement particles include reflective particles and anti-skid particles.

An improved method for manufacturing a continuous self-healing barrier film is provided. The method includes slot-die coating opposing sides of a separator substrate with a curing agent slurry and a curable resin slurry using a single-sided coating line or a tandem coating line. The method also includes sequentially interleaving inner and outer protective layers via a continuous roll-to-roll process to create a multi-layered barrier film. The barrier film can optionally be formed into a barrier envelope, and an insulating core material can be inserted into the barrier envelope to define an enclosure. Evacuating and sealing the enclosure along a perimeter of the barrier envelop forms a self-healing vacuum insulation panel with excellent properties for use as a building material and in refrigeration systems, for example. The barrier film can alternatively be used in the manufacture of tires, roofing, cargo containers, food packaging, and pharmaceutical packaging, for example.
