METHOD OF MAKING A COMPOSITE ARTICLE

摘要

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.
