Abstract
A flexible energy absorbing sheet material in which a dilatant material (6) is impregnated into or supported by a resilient carrier (1). The dilatant material remains soft until it is subjected to an impact when its characteristics change rendering it temporarily rigid, the material returning to its normal flexible state after the impact. The carrier can be a spacer fabric, a foam layer or modules or threads of dilatant material contained between a pair of spaced layers. Methods of manufacturing the energy absorbing sheet are also disclosed.
Claims8
A flexible energy absorbing material comprising a resilient carrier with voids or cavities therein, said carrier being coated or impregnated or combined with a dilatant material, wherein the resilient carrier supports the dilatant material and the resilient carrier is a spacer fabric comprising a resilient core sandwiched between a pair of covering layers.
