Abstract:
Multilayer riblet applique and methods of producing the same are described herein. One disclosed example method includes applying a first high elongation polymer material to a web tool, where the web tool is to be provided from a first roll, and heating, via a first heating process, the first high elongation polymer material. The disclosed example method also includes applying a second high elongation polymer material to the first high elongation polymer material, and heating, via a second heating process, the second high elongation polymer material. The disclosed example method also includes applying, via a laminating roller, a support layer to the second high elongation polymer material.
Abstract:
Color applications for aerodynamic microstructures are disclosed herein. One disclosed example apparatus includes an aerodynamic microstructure of a vehicle, sub-microstructures superimposed on the aerodynamic microstructure, and a color application defined on or within the microstructure.
