The present invention relates to an energy absorbent medium which is compliant and conformable in the absence of an applied force, and stiffens in response to the rate of an applied force to dissipate energy. The medium comprises a blend of a polymer and a lubricant incompatible with the polymer to produce a conformable absorbent which exhibits dilatant (shear thickening) characteristics under high rates of force or stress. The polymer has reformable sacrificial chemical bonds which are broken under a high rate of deformation and which reform under static conditions. Suitable polymers for the invention include polyborosiloxanes. Applications for the medium include absorbent for sports padding, athletic equipment, motor vehicle seats, bulletproof vests, medical equipment, industrial equipment, weaponry, and playing fields.
An impact energy absorbent medium comprising at least one polymer which has energy absorbing properties and dilatant viscoelastic flow properties, and a lubricant;
An impact energy absorbent medium comprising at least one polymer which has energy absorbing properties and dilatant viscoelastic flow properties, and a lubricant;
An impact energy absorbent medium comprising at least one polymer which has energy absorbing properties and dilatant viscoelastic flow properties, and a lubricant;
A method for forming an impact energy absorbent medium comprising the step of blending at least one polymer which has energy absorbing properties and dilatant viscoelastic flow properties with a lubricant;
An impact energy absorbent medium comprising at least one polymer which has energy absorbing properties and dilatant viscoelastic flow properties, and a lubricant;
A padded sports article comprising a containment boundary surrounding an impact energy absorbent article containing an impact energy absorbent medium, said impact energy absorbent medium containing a polymer and a lubricant in admixture, said polymer having energy absorbing properties and dilatant viscoelastic flow properties, said impact energy absorbent medium including a quantity of fibrous filler, further wherein said fibrous filler is a fibrous material wettable by either the polymer or the lubricant or both, and said medium being further characterized in that, notwithstanding the presence of both the polymer and the lubricant, the impact energy absorbent medium is a highly viscous fluid which does not exhibit flow at room temperature unless a force is applied.
