  • a shear-thickening fluid (which may be a gel) could be located in some or all of the voids to provide some blast protection.
  • the shear- thickening fluid exhibits increased viscosity when subjected to strong shear forces, for example in a blast situation. This feature shows particular suitability for use in a wall structure, as part of a blast-strengthened structure.

  • concentrated colloidal suspensions can be formed into transient aggregates, or "hydroclusters,” that can dramatically increase the viscosity of the fluid. This process can absorb energy and if in a gel form in the panel would be able to enhance its blast absorption capability.
