Abstract: Improved composite armor designs uses optimally shaped ceramic pellets, a specific stacking geometry and a web system for patterning the pellets, improving manufacturability, and providing additional structural reinforcement. Lightweight, composite ballistic armor according to the invention may comprise an array of ceramic pellets, each pellet having a front surface, a back surface and a longitudinal centerline, and wherein the front surface of each pellet is intentionally convex. The front surface of each pellet may be hemispherical, in which case the cross-section of the pellet taken perpendicular to the centerline may be oval-shaped. Alternatively, the front surface of each pellet may be elliptical, in which case the cross-section of the pellet taken perpendicular to the centerline may be circular. In the preferred embodiment, the back surface of each pellet is formed at the same angle relative to its centerline, with the pellets being arranged with the flat surfaces lying in a plane. The pellets may be arranged in a square matrix, or may be arranged in a hexagonally close-packed matrix. The array of pellets may be embedded in a hardened matrix material, and/or tied together with netting material.

Abstract: Improved composite armor designs use optimally shaped ceramic pellets and a web system for patterning the pellets, improving manufacturability, and providing additional structural reinforcement. The result is lightweight, composite hybrid structures for ballistic protection particularly suited to tactical ground vehicles. The preferred embodiment is a combination of three major components: 1) an optimally designed web system that allows armor tiles to be attached to it and that can be easily integrated with existing vehicle structures; 2) an advanced composite armor unit using a patent-pending BTR (Bio-mimetic Tendon-Reinforced) material as the supporting structure; and 3) optimally placed “waiting materials” which can provide enhanced ballistic impact resistance, energy absorption capability and structural integrity. These “waiting materials” are structural members that are not active at the beginning of the ballistic impact, but become active when needed or the active members have failed.

Abstract: Stents of the type used to treat and prevent localized flow constriction in body vessels are based upon negative Poisson's ratio (NPR) structures. An auxetic stent constructed in accordance with this invention comprises a tubular structure having two ends defining a length with a central longitudinal axis and an axial view defining a cross section. The tubular structure is composed of a plurality of unit cells with two different configurations, called V-type and X-type. In V-type auxetic stents, each unit cell comprises a pair of side points A and B defining a width, a first pair of members interconnecting points A and B and intersecting at a point C forming a first V shape, and a second pair of members interconnecting points A and B and intersecting at a point D forming a second V shape. In X-type auxetic stents, each unit cell comprises eight points from A to H defining an outline of the unit cell. Eight straight or curved members interconnecting points A and B, B and C, C and D, C and E, E and F, F and G, G and H, G and A, respectively, forming the X-type unit cell. In both configurations, the unit cells are connected in rows and columns, such that compression of the structure between the two ends thereof causes the cross section of the structure to shrink in size. The auxetic structure configurations invented can also be used, with similar dimensions or significantly different dimensions, for other applications, such as in a nano-structural device, a tubal fastener design, or in an application associated with a large oil pipe or other pipelines.

Abstract: Biomimetic tendon-reinforced” (BTR) composite structures feature improved properties including a very high strength-to-weight ratio. The basic structure includes plurality of parallel, spaced-apart stuffer members, each with an upper end and a lower end, and a plurality of fiber elements, each having one point connected to the upper end of a stuffer member and another point connected to the lower end of a stuffer member such that the elements form criss-crossing joints between the stuffer members. The stuffer members and fiber elements may optionally be embedded in a matrix material such as an epoxy resin. The fiber elements are preferably carbon fibers, though other materials, including natural or synthetic fibers or metal wires may be used. The stuffer members may be rods, tubes, or spheres, and may be constructed of metal, ceramic or plastic. The stuffer members are preferably spaced apart at equal distances. If the members are tubes, the fiber elements may be dressed through the tubes. Alternatively, the fiber elements may tied to the ends of the stuffer members and/or to each other at the joints. Both linear and planar structures are disclosed.
