Abstract
A device includes a cylindrical lattice structure inside of a cylindrical tube. The cylindrical lattice structure includes compartmentalized one or more longitudinal flowable paths formed by an additive manufacturing process. A material is introduced in a flowable state into one or more upper apertures of the one or more longitudinal flowable paths to fill the cylindrical lattice structure in a compartmentalized arrangement that provides stiffness to the device.
Claims11
A device comprising:
- a cylindrical lattice structure of compartmentalized two or more longitudinal flowable paths formed by an additive manufacturing process;
- and
- a cylindrical tube that receives the cylindrical lattice structure;
- and
- two different materials comprising a binary explosive introduced in a flowable state into respective adjacent upper apertures of the corresponding two or more longitudinal flowable paths to fill the cylindrical lattice structure in an alternating, compartmentalized arrangement.

A method comprising:
- forming a cylindrical lattice structure of compartmentalized two or more longitudinal flowable paths by an additive manufacturing process;
- inserting the cylindrical lattice structure into a cylindrical tube;
- and
- introducing the material by separately introducing two different materials comprising a binary explosive each in a flowable state into respective adjacent upper apertures of the corresponding two or more longitudinal flowable paths to fill the cylindrical lattice structure in an alternating, compartmentalized arrangement, the two different materials react when mixed as a result of fracturing the cylindrical lattice structure.

A munition comprising:
- a cylindrical lattice structure of compartmentalized one or more longitudinal flowable paths formed by an additive manufacturing process;
- and
- a cylindrical tube that receives the cylindrical lattice structure;
- an explosive material that is introduced in a flowable state into one or more upper apertures of the one or more longitudinal flowable paths to fill the cylindrical lattice structure in a compartmentalized arrangement that provides stiffness to the munition.
