Abstract: A method of making a composite article involves first forming an intermediate substrate. The intermediate substrate can be formed from fibers and an uncured thermoset polymer composition followed by partial cure, or from fibers and an uncured thermoset polymer composition followed by cure of the thermoset polymer composition and deposition of a thermoplastic on the surface of the substrate, or from fibers and an uncured thermoset polymer composition followed by cure and exposure of the substrate to organic solvent, a plasticizer, moisture, and/or heat. The intermediate substrate prepared according to any of the above techniques is then subjected to cold gas spray deposition to deposit a metal layer onto the intermediate substrate. In the case where the substrate was formed by partially curing a thermoset polymer composition, the metal-coated partially-cured thermoset polymer substrate is then fully cured.

Abstract: A method of measuring the adhesive strength of polymer materials that are arranged in a combinatorial library which involves providing a lens array having a plurality of individual lens elements on a surface thereof and a substrate. A pattern of different polymer materials, processing variables or environmental conditions is applied to either the individual lens elements of the lens array or to the substrate. The individual lens elements of the lens array are brought into contact with the substrate and, as the lens array and substrate are separated from one another, changes in contact area of the individual lens elements with the substrate are monitored and used to calculate the adhesive strength of the polymer.
