Abstract
A munition includes a triply periodic minimal surface (TPMS) structure attached to an inner surface of a cylindrical tube. The TPMS structure is formed by an additive manufacturing process to promote fluid permeability and to reduce pressure drop to prevent trapped air and maximize surface area contact at a structure and liquid interface. An explosive material is introduced into one or more upper apertures of the TPMS in a flowable state to fill the TPMS structure n a compartmentalized arrangement that provides stiffness to the munition.
