Abstract
A composite material which is elastic, which exhibits a resistive load under deformation which increases with the rate of deformation, which is unfoamed or foamed, comminuted or uncomminuted and which comprises i) a first polymer-based elastic material and ii) a second polymer-based material, different from i), which exhibits dilatancy in the absence of i) wherein ii) is entrapped in a solid matrix of i), the composite material being unfoamed or, when foamed, preparable by incorporating ii) with i) prior to foaming.

-40. (canceled)
A method of protecting a subject from an impact comprising
- a) providing an impact protection system comprising an unfoamed composite material, the composite material being elastic and exhibiting a resistive load under deformation which increases with a rate of deformation, the composite material comprising (i) a solid matrix comprising a first polymer-based elastic material and (ii) a second polymer-based elastic material different from (i) which exhibits dilatancy in the absence of the first polymer-based elastic material, wherein the second polymer-based elastic material is entrapped in the solid matrix in an intimate admixture;
- and
- b) placing the impact protection system on the subject to protect the subject from the impact.
