摘要:
This invention is directed to energy absorbing or dissipating composite materials used to reduce structural damage from explosive blast energy and ballistic projectiles, either separately or in combination, and to methods of employing such materials. More particularly, this invention is directed to a blast damage suppression and/or ballistic shielding material comprising at least three independent layers; a layer comprising fiber based panels; a spray foam coating material and a coating layer comprising an elasto-plastic material.
摘要:
A blast protecting panel for interior portions of building windows (27) includes a blast-shielding panel (6) of a high tensile fiber woven in an open weave fabric in such a manner whereby a high degree of light is transmitted through the fabric while still allowing see-through visibility. The fabric is mounted using a retention system, which can be either fixed or dynamic, allowing the fabric to unwind and billow out into the building, retaining flying glass and debris. The retention system preferably includes fixed upper and dynamic lower tension retainers (7) around which a length of fabric is wound and which allows the fabric to unwind therefrom without becoming detached from the retainer case (5) or from the surface to which the retainers are mounted.
摘要:
A target apparatus comprising a bag (14) formed of flexible material, means (12) for introducing compressed air or gas to the interior of said bag to cause the bag to be inflated and a projectile detection arrangement adapted to detect a projectile fired at the inflated bag, the projectile detection arrangement comprising at least one transducer (18,19) responsive to an airborne pressure or shock wave generated by the projectile.

A thermoplastic composite article comprising a porous core layer comprising a plurality of reinforcing fibers, a lofting agent and a thermoplastic material is provided. In certain instances, the article further comprises a skin layer disposed on the core layer and an adhesive layer between the core layer and the skin layer. In some configurations, the adhesive layer comprises a thermoplastic polymer and an effective amount of a thermosetting material to provide a post-molding peel strength between the skin layer and the post lofted core layer of at least 0.5 N/cm (in either or both of the machine direction or cross direction) as tested by DIN 53357 A dated Oct. 1, 1982.
摘要:
An anti-ballistic barrier comprising at least one furniture unit including: a top; a base; an anti-ballistic arrangement including an anti-ballistic material, the anti-ballistic arrangement having at least a portion extending between the top, and the base; and a mobility arrangement which, in use, enables each furniture unit to be moved between at least two positions, comprising a utility position, in which each furniture unit can be used in its typical furniture usage, and a defence position, in which each furniture unit can be used as a barrier to obstruct an opening such as a doorway, a passageway, a window or a service opening.
