HYBRID PROTECTIVE COMPOSITE Russian patent published in 2003 - IPC

FIELD: protective composites possessing stableness to the impact by a knife and ice-ax sword bayonet. SUBSTANCE: the protective composite structure contains a great number of layers of fabric containing polybenzoxazole and polybenzothiazole fibers resistant to penetration of a knife and an ice-ax sword-bayonet, and a great number of layers of a net of fabric fibers protecting against a ballistic impact. The structure has an external surface and an internal surface, the great number of layers of closely-woven fabric that is resistant to penetration of a knife-and an ice-ax sword bayonet is positioned closer to the external surface as compared with the great number of layers protecting against a ballistic impact. EFFECT: enhanced resistance to penetration of a knife and an ice-ax sword bayonet and to a ballistic impact. 17 cl, 1 dwg, 2 ex
