FIELD: safety products. ^ SUBSTANCE: group of inventions pertains to body armor facilities. Production method of helmet of polymer composites includes location of shock damper between domical protective cover and helmet inner. Damper is produced by cutting out of a blank part in the shape of chamomile with 4-8 equally spaced meridian incisions of elastic thermoplastic foam plastic with the width of (1.05Ç2.2)s, where s - width of protective cover. Equally spaced openings with d = (0.6Ç1.5)s diametre are made in the blank by arranging them at l = (1.05Ç2.2)d from each other in the tops of mutually adjoining equilateral triangles. Thereafter blank is assigned dome-shape by thermal processing in the domical tool set deforming openings into a cone-shape. Helmet of polymer composites contains a protective cover, helmet inner and arranged in between of them damper produced by the above stated method. ^ EFFECT: invention is aimed at increasing reliability of helmet, reducing weight of the damper, decreasing after-penetration edge on the protected object. ^ 3 cl, 7 dwg |
