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

Abstract RU 2205328 C1

FIELD: reinforced high internal pressure shells. SUBSTANCE: proposed shell is made in form of load-bearing framework with cylindrical section, end convex bottoms and flanges in their pole holes. Said framework is formed by combination of groups of layers of spiral and circular tapes with unidirectional high-modulus filaments. Circular projection with circular groove in its outer surface is formed at pole hole. Filaments are fastened by means of polymer binder. Framework is lined with protective coat. Thick-walled circular member made from high-modulus material is mounted in circular groove and is locked over outer surface by at least one layer of spirally crossing tapes. Inner diameter of circular member is equal to dpole+(2,0-3,0)δtape, where dpole is present diameter of pole hole and δtape is width of spiral tape at pole hole. EFFECT: enhanced strength of shell. 3 cl, 3 dwg
