Zusammenfassung: | FIELD: armament; equipment.SUBSTANCE: invention relates to the field of armament and equipment, to the protective equipment development, and can be used for the armored helmets manufacturing, made of layered polymeric composite materials with dampers on the under headpiece device. Disclosed is method, in which the under headpiece device is fixed inside the domed protective helmet. Attaching the Velcro tapes with micro-hooks thereto, on which, in turn, fixing cushions. Cushions are pressed in the mold (7). For this, on the press cold plate (8) arranging the mold (7) die (9) of thermo-insulating material with recess for the cushion shell (11) and a step for the cushion flange formation. In the step along its entire area, placing the metal frame (14), and then the dividing frame (15). In the die (9) cavity, embedding the shell (11) of polyester pile fabric with pile outwards. Knitted fabrics is also placed on the flange material formation frames (14) and (15). After the frames (14) and (15) for the tolerance (16), into the shell (11) the damper made of polyurethane foam (18) and expanded polypropylene (19) plates is installed. On the damper, the shell (11) knitted flange (20) and the tolerance (16) placing the adhesive fleece (21) with polyester fibers. On the fleece (21), placing the polyamide pile fabric cushion base (24) with pile outwards with the base (24) flange material (23) and the tolerance (16) formation. On the flange (23), placing the identical separation (15), and then metal (14) frames. Inside the frames (14) and (15), along the opening entire area, placing the thermal insulation plate (25). Covering the mold (7) with the press heated by the plate (26) and holding under realized in the frames area pressure. Ensuring the flange pressing with the knitted fabric and polyamide material gluing due to the knitted fabric and fleece fabric (21) partial melting and its embedding into the polyamide material structure. Also, enabling the polyamide material nap fibers semi-plasticity with their residual deformations until height of 20-50 % of their original size in the flange area (23). Removing cushion from the mold (7). Cutting the tolerances (16) along the metal frame (14) outer edge. Fastening the cushions with polyamide pile on the Velcro micro hooks. Also disclosed is the armored helmet from polymeric composites.EFFECT: enabling the armored helmet more technological design, increased operation reliability and comfort of use.4 cl, 8 dwg
