"Synthesis of Composites for Use in Rapid Manufacturing of Electronic/Microwave Devices"
Three filled polymeric composites were developed for use in periodic structures to replace metallic parts in electronic and microwave applications. The composites were developed to be conductive or to have high dielectric properties for efficient operation in the periodic structures. The composites are produced by filling thermoplastic matrices with ceramic powder, carbon and metallic fibers to achieve the desired properties. The production, testing and classification of these composites and their resulting electronic and dielectric properties will be presented. The formation of the final 3-D periodic structures with these composites was investigated. The processes of injection molding and fused deposition modeling were tested and evaluated for the rapid manufacturing of the composites.
