Abstract: Negative Poisson's ratio (NPR) or auxetic are used to make lightweight wheels and runflat tires. The NPR tires can be tailored and functionally-designed to optimally meet the runflat requirements for both military and commercial vehicles. NPR-runflat tires may be fabricated using standard materials and simple manufacturing processes, resulting in low-cost and high-volume production. In preferred embodiments the runflat tire designs are fully compatible with Central Tire Inflation Systems (CTIS), while providing a performance equivalent to current military vehicle solutions but at half the weight. An auxetic wheel according to the invention comprises a line defining an axis of rotation; and a plurality of concentric rings of unit cells surrounding the axis, each unit cell being constructed of a plurality of members defining a Negative Poisson's Ratio (NPR) structure. The outermost ring of unit cells is arranged to facilitate rolling terrain contact, such that the stiffness of the structure in the localized region of loading due to terrain contact increases as the wheel rotates. A layer of material may be disposed between the concentric rings of unit cells which in preferred embodiments comprise a plurality of nested-V shapes. A cover may be provided over the outermost ring of unit cells forming a tire which may, or may not, be inflated.

Abstract: Biomimetic tendon-reinforced” (BTR) composite structures feature improved properties including a very high strength-to-weight ratio. A basic structure comprises a plurality of spaced-apart stuffer members, each having a first end and a second end defining a length. A plurality of tendon elements interconnect with the first and second ends of the stuffer members in alternating fashion, such that the tendon elements criss-cross each other between the stuffer members. A first panel is bonded or attached to the first ends of the stuffer members, and a second panel is bonded or attached to the second ends of the stuffer members. In the preferred embodiments, the first panel, the second panel, or both the first and second panels are curved. An efficient manufacturing process based upon hollow stuffers and tendon elements in the form of bent wires is also disclosed.
