A double truss structural armor component includes a first face sheet, an intermediate sheet opposing the first face sheet, a first truss core member sandwiched between the first face sheet and the intermediate sheet, a second face sheet opposing the intermediate sheet, a second truss core member sandwiched between the second face sheet and the intermediate sheet, and laminate materials disposed within interior flutes of the first and second truss core members. The first tress core member has a flute axis. The second truss core member has a flute axis which is oriented in a range of about 45°to 90°from the flute axis of the first truss core member. Thus, a biaxially redundant load path is formed. The first and second face sheets, the intermediate sheet, and the first and second truss core members are formed of high toughness, high strength titanium alloys. The laminate materials which are within the interior flutes of the truss core members are bonded to portions of the flutes that are adjacent to the intermediate sheet. The laminate materials have high energy of break properties. During impact of a ballistic fragment, one of the face sheets slows down the fragment and flattens and further fragments the fragment. When the resulting fragments impact the laminate materials, their energies are absorbed by the laminate materials by high strain deformation of the laminate materials in biaxial directions. Thus, the fragments are brought to rest and are prevented from penetrating the other face sheet. During impact of a blast wave, the energy wave is partially absorbed by one of the face sheets, deforming and transferring load to the truss core members. These members deform in a buckling mode in biaxial directions, thereby absorbing the blast energy in a spring-like manner, preventing fracture of the other face sheet.
