    Abstract: Technologies are generally described for hybrid acoustic damping materials that may be used in noise, vibration, and harshness mitigation. In some examples, solvated acrylic, silicone, and/or urethane materials may be blended in selected proportions to form a hybrid acoustic damping material. Characteristics of the components of the hybrid acoustic damping material such as viscosity and proportions may be selected for a desired composite loss factor vs. temperature characteristic of the material. In some examples, a broad temperature range of damping or a targeted temperature region may be achieved based on the composition of the hybrid acoustic damping material. To achieve a uniform stable blend with a consistent viscosity, individual component materials may be selected with similar molecular weight/viscosity. Compatible solvents may be added during blending of the components. In various example applications, the hybrid acoustic damping material may be used in vehicle brake applications to reduce brake noise/vibration.

    Abstract: A method for coating a part that has an asymmetrical edge by attaching the part to a part holder, placing a film between the part and a mandrel, rolling the part over the mandrel such that the asymmetrical edge of the part contact the film, and, moving one or both of the mandrel and the part holder in an angular relationship to one another as the angle of the part's asymmetrical edge changes. A film dispenser and a film retriever are provided and preferably they move cooperatively in at least two dimensions with respect to the part holder. The film has a first edge and a second edge, and the film can be a decorative coating, a protective coating or combinations of these. The film dispenser holds the first edge of the film, the film is positioned between the mandrel and the part holder and the film retriever holds the film second edge.
