A light weight pre-stressed antiballistic article including a monolith ceramic plate / tile bonded to a thin lightweight thermal expansion material with an adhesive, characterized, in that the thermal expansion material has a thermal expansion coefficient at least 50% higher than the ceramic plate / tile, and the thermal expansion material is bonded to either the front face, back face or both faces of the ceramic plate / tile at a bonding temperature of between 50° C. and 250° C. with adhesive and subsequently cooled, whereby upon cooling, the bonded thermal expansion material contracts to a greater extent than the ceramic plate / tile, exerting compression stress on the ceramic plate / tile.

Structures based upon periodic cellular materials that provide a potential for defeating combinations of both air blast loading and ballistic attack either sequentially or simultaneously, or combination of both. The cellular structures may also be configured to meet the stiffness and strength support requirements of particular vehicle or other applications, systems or structures. The armor is therefore potentially able to support normal service loads and defeat blast and ballistic threats when necessary. The structure provides for using efficient load support capabilities of the material (without a high armor protection level) in low threat conditions, as well as the ability to modify the system to increase its level protection to a desired or required level. This would reduce the weight of the protection system in normal (low threat) conditions which reduces vehicle wear and tear, as well as cost savings in fabrication of applicable structures or systems.

According to some embodiments, there is provided a ballistic-resistant composite including a plurality of large denier per filament (dpf) yarns. The large dpf yarns may have a “Composite-Armor dpf factor” (CA•dpf) of greater than or equal to 6.9.

The invention discloses an anti-collision vessel with an elastic frame structure. The anti-collision vessel with the elastic frame structure overcomes the defects that at present, after ships collide with each other, the ships crack and are damaged, and weld joints are disengaged. The anti-collision vessel with the elastic frame structure is characterized in that a vessel body structure is an integrated elastic frame type structure, a hull, a deck and a framework of the vessel are made of elastic high-strength materials, the hull is in the shape of an oval arc, focal points of stress are removed, the framework is of an arc shape or wavy shape according to the shape of the hull, and the deck is of a double-layer structure. The same principle can be applied to modification that an elastic protective layer for collision resistance is additionally arranged on an existing ship, and the collision resistance performance of the ship can be greatly improved. The whole vessel has the micro elastic deformation function, after the nose or the stern or the two sides of the vessel are collided, the vessel body can have corresponding micro elastic deformation under the action of impact force, instantaneous impact energy in the collision process can be buffered and absorbed, and the collision resistance security coefficient of the vessel can be greatly increased. The elastic structure of the vessel cannot influence normal traveling and the bearing capacity of the vessel.

The present disclosure relates to a shock absorbing arrangement suitable e.g. for ship installed structures comprising a rod, a resilient member arranged in connection to the rod, a structure element and a locking member arranged in connection to the structure element. The locking member is arranged to detachably lock the structure element at a resting position at the rod and the locking member, or the structure element, is supported by the resilient member. The resilient member is configured such that a spring force of the resilient member acts to maintain the structure element essentially at the resting position at the rod. The locking member is further configured to release the structure element from the resting position when being exposed to a force exceeding a predetermined holding force, whereupon the resilient member acts to reinstate the locking of the structure element at the resting position at the rod. The present disclosure further relates to a shock absorbing structure comprising such shock absorbing arrangements.

The invention relates to a sensor fastener arrangement (10a-f) for holding a sensor device (3). The sensor fastener arrangement (10a-f) comprises a plurality of fastener elements (20a, 20b). The fastener elements (20a, 20b) are configured to arrange the sensor device (3) to a platform (1). Respective fastener element (20a, 20b) is rigid in a first state and reversibly deformable in a second state. When the platform (1) of the sensor device (10a-f), and / or the sensor device (3), is exposed to an impact force, in turn exposing a fastener element (20a, 20b) to a compressive force exceeding a critical load of that fastener element (20a, 20b), the fastener element (20a, 20b) goes from being in the first state to temporarily being in the second state. Thereby the fastener element (20a, 20b) goes from having a first rigid shape to temporarily being reversibly deformed, after which, when the impact force is terminated, the fastener element (20a, 20b) goes from temporarily being in the second state back to being in the first state. Thereby the fastener element (20a, 20b) goes from temporarily being reversibly deformed to having the first rigid shape.

A security device comprising: a barrier, and a plate, wherein the barrier and the plate are releasably attachable to each other, and when the barrier and plate are attached the device comprises a slot for receiving a rail and the device may hang on a rail with the rail received in the slot, and the barrier protrudes in a horizontal direction, perpendicular from a plane extending downwardly from the rail, to provide an overhang; and wherein at least a portion of the plate is made from a bullet-resistant material.

The invention discloses a double-side anti-layering sandwich plate with an oblique rib plates, comprising an upper panel, a lower panel and a core material filled between the upper and lower panels. The inner side of the upper panel is uniformly provided with a plurality of upper rib plates arranged obliquely, and the inner side of the lower panel is uniformly provided with a plurality of lower rib plates arranged obliquely; the friction coefficient between the core material and the upper rib plates is mu, and the oblique included angle between the upper rib plates and the upper panel is smaller than tan-1mu, and the friction coefficient between the core material and the lower rib plates is mu'; and the oblique included angle between the lower rib plates and the lower panel is smaller thantan-1mu'. The double-side anti-layering sandwich plate with an oblique rib plates overcomes the layering phenomenon of the sandwich plate by changing the structure form of the traditional sandwich plate and obviously improves the anti-penetration performance of the sandwich plate, thus not only increasing the protective performance of the ship, but also reducing the weight, and improving the comfort and safety. The double-side anti-layering sandwich plate with an oblique rib plates has a convenient processing method and a lower cost, and is applied to the fields of ship structure, building structure, armored vehicle and the like.
