Claim 12:
13. A multilayer article comprising a plurality of layers at least two of which are absorber layers for dissipating kinetic energy of a moving object and further comprising one or more insulating layers comprising aluminized biaxially-oriented polyethylene terephthalate, wherein one of the absorber layers is an interior absorber layer disposed within the interior of the plurality of layers and another of the absorber layers is an outer absorber layer forming an exterior layer, wherein the one or more insulating layers is disposed between the interior absorber layer and the outer absorber layer, wherein each absorber layer comprises a shear thickening fluid intercalated into a fabric comprising a plurality of fibers having a tensile strength of at least about 1 GPa and a specific strength of at least about 1,500 kN*m/kg, wherein the shear thickening fluid comprises at least one low volatility carrier fluid in which is suspended particles at a concentration in the range from about 40% to about 85% by weight, and wherein the suspended particles and shear thickening fluid remain in a flowable form after intercalation.
