Abstract Scope |
PrintCasting is a recently developed hybrid additive manufacturing process that can be used to form architectured composites, where constituents are patterned in a periodic array with a characteristic length scale on the order of several hundred microns. We can utilize this fine architectural control offered by PrintCasting to fabricate munitions casings with tailorable interpenetrating mesostructures, allowing precisely controlled shock dynamics and fragmentation behavior. In this study, we examine the effect of mesostructure on the dynamic behavior of PrintCast composites of steel and aluminum with interpenetrating BCC and TPMS mesostructures. Plate impact experiments reveal the relationship between composite geometry and bulk shock behavior. Fragmentation tests with high-rate imaging and pressure sensing are used to compare conventional monolithic and PrintCast munitions casings. These experiments together demonstrate the ability to tailor the dynamic behavior of composites through PrintCasting. |
