FIELD: explosives.
SUBSTANCE: explosion-proof material contains laminated material (11) with large volume of cavities. At that, laminated material (11) is folded to multi-layer material body (1) by using one edge (12) of this material as an axis and in the direction perpendicular to edge (12). In order to reinforce and support material body (1), frame (13) is put into the slot between any two layers of multi-layer laminated material (11) of material body (1), where frame (13) is formed by interweaving of frame (131) and stiffener ring (132). At that, stiffener ring (132) is arranged in the middle of frame (131) and attached to it, and shape of frame (13) corresponds to the shape of material body (1).
EFFECT: higher material strength and protection against deformation and failure.
