The paper presents the results of experiments for determination of response of spherical shells having load-bearing layer from fiber glass under radially symmetrical inner explosive loading. We carried out assessment of dynamic strength of two shell types with diameter of 500 mm, which differed in the scheme of fiber glass layer coiling. It was demonstrated that a shell with more even thickness (of 15-20 mm) of load-bearing fiber glass layer has significant advantage. Such a sheath has approximately twofold reserve of strength during explosion of a charge equal in energy to 1. 4 kg of trinitrotoluene in its geometrical center. It has been found that transition from one-axial strains, which are realized under explosive loading of a cylindrical shell, to two-axial strains, when spherical shells are used, does not change the value of limiting strains of fiber glass (on the destruction threshold). This value is determined by limiting strains of a glass thread. It is equal to 4-5 %. Tested spherical shells from fiber glass reinforced by steel layer allow to obtain record high value of the explosion-proofness property, i. e. relation between the high-explosive charge mass, where explosion of this high-explosive charge is confined inside of the sheath cavity, and mass of this shell. It is equal to 3-6 %.
