Personal protection system such as flak jacket incorporates impact absorbing/damping material in form of viscoelastic gum with variable rheological response to shearing forces

摘要

The personal protection system incorporates a material (5) that absorbs and/or damps impacts and is in the form of a viscoelastic gum with a rheological response that varies with the shearing force to which it is subjected, becoming rigid when it is subjected to a dynamic stress and returning to a fluid when the stress ceases. The material (5) is enclosed in a pouch (4) or envelope of a supple and impermeable material including thermo-weldable synthetic or carbon fibres and located on the side of the garment or article that is in contact with the wearer's body, behind a number of layers (3) of a synthetic material.
