<p>PURPOSE: A protection structure for national defense is provided to partition a plurality of cells of a hollow structure by cell walls and form a hollow in inside so that proper rigidity and strength are maintained while whole weight is reduced. CONSTITUTION: A protection structure(100) for national defense comprises a hollow structure(110), a cladding unit(120), and a filler material. A plurality of cells(112) of the hollow structure is hollow and divided by cell walls(113). The plurality of cells is aligned in a three-dimensional set pattern. The cladding unit encloses the exterior of the hollow structure. The filler material is selectively charged in the hollows of the cells.</p> |
