Additive Manufacturing for Lethal Materials

Develop applied research programs into computational design for propulsion. Research focuses on developing and utilizing computational techniques to optimize multi-physics phenomena, such as structural/combustion, which are enabled by state-of-the-art manufacturing processes. AM of rocket and gun propellant enables use of more energetic materials, higher loading densities, and novel geometric configurations that allow tailored burn rate profiles. The AM techniques for energetics are based on polymer AM approaches, thereby making the polymer binder chemistries a critical component of the research. Research focuses on designing multiple reactive binder chemistries to optimize mechanical and high-G performance of printed architectures by improving particle-to-binder interactions, layer-to-layer adhesion, and tailorability of binder mechanical properties. Energetic monomers can be formulated into the binder chemistries to increase energy or reduce solids loading to improve mechanical performance
