FIELD: construction.SUBSTANCE: anti-ricochet and anti-fragmentation protection comprises a frame, outer (1) and inner (6) protections installed on it. The inner protection (6) is fixed to the frame by means of a cord pulled via eyelets on the protection and brackets on the frame. The inner protection (6) comprises a composition of sheets of crease-resistance (8) and energy-absorbing (9) materials. The energy-absorbing material is ultra-high molecular polyethylene, Kevlar, glass-cloth-base laminate and other materials with high impact strength.EFFECT: reduction of damage from penetration before exploding, retention of a larger part of fragments and prevention of bullet ricochet against inner walls of a compartment due to joint usage of external protection, crease-resistance and energy-absorbing materials.5 cl, 6 dwg |
