HYBRID COMPOSITE MATERIAL FOR HIGH-PRESSURE SHELL STRUCTURES Russian patent published in 2019 - IPC B32B5/26 

FIELD: chemistry.

SUBSTANCE: invention relates to polymer composite materials (PCM), in particular to hybrid composite materials for making high-pressure shell structures. Hybrid composite material is based on polymer binder and reinforcing aramide filler consisting of Rusar-S threads with microstrength tensile strength of 580–800 kgf/mm² and modulus of elasticity 15,500–17,000 kgf/mm² and Rusar-NT threads with microplastic tensile strength of 550–700 kgf/mm² and modulus of elasticity of 17,000–20,000 kgf/mm², wherein strength and modulus of elasticity of annular layers of composite material is 240–280 kgf/mm², respectively and 12,000–14,000 kgf/mm².

EFFECT: invention can be used for production of rocket and space equipment, in aviation, shipbuilding and helicopter building.
