Abstract:

One of the major barriers that restricts the expanded use of high-performance, resin-matrix composite materials in both government and commercial applications is the lack of a reliable, cost-effective coating process. The desired technique must deposit a variety of protective coatings without degrading the underlying composite structure while minimizing any environmental hazards. This Phase I SBlR demonstrated feasibility of using a commercially-viable coating process, called Low Temperature Arc Vapor Deposition LTAVD, a patented variation of cathodic arc plasma deposition to apply several hard, high temperature materials on composite substrates. Three types of laminates with different surface conditions, graphite tibers, and matrix resins were used as specimens so that sample coatings for a broad range of potential composite applications were demonstrated. These results have led to expressions of possible Phase II and III support from companies in ground transportation MASCO and heat sinks for PWB assemblies AMT. MM
