METHOD FOR MANUFACTURE OF ARMOUR PANEL FROM LAYER COMPOSITES FOR FACE BOTTOM PART PROTECTION AND ARMOUR PANEL FROM LAYER POLYMERIC COMPOSITES FOR PROTECTION FOR FACE BOTTOM PART PROTECTION Russian patent published in 2017 - IPC F41H1/04 

FIELD: personal demand items.

SUBSTANCE: method for manufacture of an armour panel from layer polymeric composites to protect the lower part of the face in which 2-4 impregnated layers of fiberglass (3) are laid in the mould (2), then 12-18 ballistic layers (4) of a non-impregnated aramid fabric treated by waterproof composition with impregnation of edges (5) only for a width of 15-20 mm on the lower, lateral and temporal edges, and also with the impregnation of the zones of brackets for armour panel fastening the helmet, are laid. In the glasses area, the fiberglass is laid with an allowance for the groove on the 15-20 mm, and ballistic layers (4) - into the interior of the groove without edges impregnation, aligning the ends of these layers with the allowance level. Then, the bag is pressed uniformly to the mould and kept until the binder (17) is partially cured, after the removal of the pressure-generating device, 2-4 impregnated layers of fiberglass (18) are laid on the package covering all layers, then the final bag is pressed with uniform pressure (19) to the mould and kept until the binder (17) is cured completely to form a three-layer structure from the front (3) and back (18) shells, inner ballistic layers (4), and a rigid frame rigidly fixed to the shells, (20) along the contour of the armoured panel up to the width of the bar along the lower, lateral and temporal margins - 5-8 mm, in the glasses area - to the width of the fiberglass shelf support for the glasses - 5-8 mm, in the brackets areas - according to the areas size, and the pile formed on the lower, lateral, temporal and zones of the edge brackets during cutting is edged as a channel made of impregnated glass tape. An armour panel to protect the face bottom part is also proposed.

EFFECT: technological and high quality armoured panels are provided.
