Abstract: Cold Spray (CS) additive manufacturing utilizes highly pressurized super-heated gasses to spray microscopic particles on a substrate. These microscopic particles encompass a variety of material types including pure metals, metallic alloys, and ceramics. The kinetic energy of the particles being released upon impact forms adhesive and cohesive bonds between the substrate and powder. CS technology is a niche manufacturing technology which has new applications in the world of smart and hybrid structures. A literature review examines recent research involving CS and potential applications. In particular, the applications to Additive Manufacturing, Material Processing, Characterization, and repairability were reviewed and compared. The validity of CS and its applications are benchmarked against other manufacturing methods. Fiber Reinforced Polymers Composite laminates were sprayed with a variety of particle combinations including [Al, Zn], [Sb, Sn, Cu], [Cu, Zn] at discrete range of nozzle temperatures ranging from 200 °C to 600 °C. The samples’ electromechanical properties were examined to determine the viability of CS in additively “printing” circuits and forming bonded joints on the samples. Microscopy analysis of the samples indicates a promising path forward for implementation of CS additive in smart structures and hybrid metallic-reinforced fiber reinforced polymers.
