REINFORCED ENVELOPE FOR HIGH PRESSURE MADE FROM LAMINATE COMPOSITE (VERSIONS) Russian patent published in 2002 - IPC

Abstract RU 2190150 C1

FIELD: high-pressure made from composite laminate. SUBSTANCE: proposed envelope includes load-bearing skeleton with cylindrical section, end bottoms and flanges in their pole holes; it is formed by combination of groups of layers of spiral and circular tapes oriented in spiral and circumferential directions with unidirectional high-modulus filaments fastened by polymer binder lined by protective coat; load-bearing skeleton is formed over central zones of bottom by at least two groups of layers of spiral tapes narrowing towards pole holes at constant radius of pole hole at base of flanges increasing their width by 1.1 to 2.1 times in subsequent layers of each group; it is made from high-modulus filaments at linear density of 29 to 100 tex on base of aramide fibers and epoxy-containing binder. EFFECT: enhanced reliability and simplified construction. 4 cl, 5 dwg
