REINFORCED HIGH INTERNAL PRESSURE SHELL MADE FROM LAMINATED COMPOSITE MATERIAL Russian patent published in 2003 - IPC

Abstract RU 2205329 C1

FIELD: high internal pressure shells. SUBSTANCE: load-bearing framework of proposed reinforced high internal pressure shell has cylindrical section and end convex bottoms and flanges in pole holes. Bottoms are smoothly engageable with cylindrical section of framework over outer surface. Framework is formed by combination of groups of layers of spiral and circular tapes with unidirectional high-modulus filaments fastened by means of polymer binder; framework is lined with protective coat. Cylindrical section of load-bearing framework is provided with inner circular projection of the same length which is smoothly engageable with bottoms forming circular grooves together with it. Maximum diameter of said grooves exceeds inner diameter of circular projection of cylindrical section. Similar layers of spiral and circular tapes of cylindrical section are located in pairs on surfaces equidistant from inner and outer surfaces of shell. EFFECT: increased load-bearing capacity; enhanced weight efficiency and operational reliability. 2 cl, 2 dwg
