Abstract
A compound for protection of an object from a blast or shock wave. The compound include a matrix material and at least a first and second sets of inclusions in the matrix material that differ in size, quantity, shape and/or composition in a direction through the impact-absorbing material, the combination of which contributes to the ability of the material to exhibit at least one property that changes as the inclusions are deformed in response to a blast or shock wave.
Claims4
A method of making a blast or shock wave mitigating material, comprising:
- providing a compound that is curable to form a polymer;
- providing a mold cavity having an internal height adapted and configured to produce cured polymer suitable to be used in a helmet or as a sheet of material to be used in blast protection panel, the mold cavity configured to provide geometric features within the cured polymer;
- placing the compound in the mold cavity;
- curing the compound for at least about five minutes;
- exposing the mixture in the mold cavity to pressure less than ambient pressure after said permitting;
- removing the substantially polymerized material from the mold;
- filling the geometric features with a fluid;
- and forming the material as an interior portion of a helmet or as the blast protection panel.
