Abstract: An aramid fabric having excellent adhesion to a polyurethane matrix resin and excellent tensile strength is produced by the method including the steps of: (i) weaving a basket-structured aramid fabric by using aramid yarns as warp and weft yarns; and then (ii) dipping the woven aramid fabric in a sizing agent solution consisting of an aqueous polyurethane resin as a sizing agent and water, followed by squeezing and drying. In the present disclosure, the sizing agent is applied to the woven aramid fabric, thereby effectively preventing the deterioration in weaving efficiency. Further, the aramid fabric is woven in a basket weave, and thus the compactness of the aramid fabric is lowered and the wetting property of the aramid fabric with the polyurethane matrix resin is improved.

Abstract: A composite panel includes a ballistic fabric strike surface layer and an underlying structural armor plate layer. The structural armor plate layer is corrugated and includes a multiplicity of traversing ports. The traversing ports have sufficient lateral area to allow explosive blast deformation of the ballistic fabric through the structural armor plate layer. By selecting both relative port traversing void area and corrugation angle an effective projectile blockage is achieved. The composite shield is particularly effective in protecting personnel. Blast frequencies in the 1000 to 3000 Hz Cooper Injury Range component of the blast wave spectrum are attenuated. The panel has projectile shredding properties and has improved structural stability.

The common mounting provision includes a plurality of common mounting bosses that are arranged in a grid type pattern formed by attaching a plurality of mounting bars to an interior wall of an armored hull with each mounting bar including at least one of the common mounting bosses. The grid type pattern provides for a common spatial distance between adjacent apertures in rows and columns. When engineering changes are needed, the grid type pattern provides the engineer with known mounting bosses having a known spacing allowing the engineer to readily design the component to attach to the common mounting provision. By knowing the size and location of each mounting boss, the engineer will spend less time designing and fitting new components and will avoid having to continually update drawings to illustrate new mounting provisions.

Abstract: A wall of, for example, a bombshelter or armored vehicle, is provided with an inner and outer armor spaced from each other. This armor protection is designed to provide a deflection, respectively destruction of an impacting projectile as soon as the projectile nose has penetrated the outer armor. The arrangement is designed to permit only a relative minor destruction of the outer armor in the impacted region, so that those regions adjoining the impacted region maintain their protective structural integrity.This object is achieved in that in the partial chambers which are divided by transverse walls defining closed intermediate chambers between both armors there is disposed a material insert which explodes or bursts as a result of the penetration of the projectile, for example, a material insert consisting of an explosive, glass or ceramic material. The outer armor consists of plates which are overlappingly arranged at one of the adjoining sides and which swing outwardly.

Abstract: A system for protecting exterior building walls against damage from pressure waves generated by explosions on the building exterior. Exterior walls are constructed of multiple wall panels mounted in a circumferential framework of building elements formed by columns, a top surface of the floor below the wall and bottom surface of the floor above the wall. A series of guide tracks mounted in the circumferential surfaces extend perpendicular to the wall panel towards the interior of the building. Guide blocks on the perimeter of the wall panel engage the guide tracks so that the wall panel can slidably move along the tracks when a predetermined threshold force is applied to the exterior of the panel. An adjustable brake, on cooperating with the guide blocks and tracks, permits an accurate setting of the threshold force under which inward movement of the panel commences as well as the relatively constant force that acts during sliding.
