ARMOURED HELMET OUT OF POLYMER COMPOSITES

摘要

FIELD: personal items, clothing.;SUBSTANCE: invention refers to army requisites and outfits, to development of security facilities and can be used for fabricating of armoured helmets out of laminar polymer composite materials such as organoplastics. An armoured helmet made out of polymer composites contains layers of an exterior shell out of, for example, aramid fabric soaked with a polymer binder, hard alloy curvilinear and flat alternate insertions and layers of an interior shell layers similar to exterior layers. The insertions are made out of elementary cells secured to each other and to shells with glue chemically compatible with the shell binder. The insertions are made out of isotropic material, for example, out of ceramic. The thickness of cells corresponds to a caliber of the basic damaging element. Linear dimension of the cell exceeds its double thickness by 1.5-1.7 times.;EFFECT: creation of a helmet of upgraded reliability.;2 cl, 6 dwg
