Claims (1)

The protective shell relates to mechanical engineering and can be used in the production of containers, fuselages and other shell-type structures. The invention provides improved reliability by imparting durability to the shell when exposed to flying stones and radiation. The protective sheath of composite materials consists of outer and inner shells, an intermediate layer between them of foam, reinforced with an arched system of intersecting tapes of high modulus fibers, and end frames. The outer and inner shells are made in the form of concentric continuous layers of tape helical spirals of two types with the slopes of their turns 86 - 88 °. Part of the layers of the inner shell spirals on the inner surface side are made of woven tapes of carbon fibers and tapes of aramid fibers layered with elastic-elastic layers of rubber type. The arched system of the intermediate layer of foam and the layer of helical spirals of the outer shell from the side of the intermediate layer are made of tapes of aramid fibers. The remaining layers of the tape helix spirals of the inner and outer shells are made of glass-glass fabric with aramid fibers as the warp threads located in the direction of the helix coils.
