SHELL OF COMPOSITE Russian patent published in 2014 - IPC F16L9/12 

FIELD: transport.

SUBSTANCE: shell of composite is intended for use in aircraft and aerospace engineering. Foam plastic ply is arranged between rings 1, 2 and shell and composed of basic parts 3 to make intersecting channels. Said channels accommodate rib-like cellular structure 4 extending to edge frames 5. The latter are made of the sets of solid circular plies 9, 10 arranged across unidirectional bundles and/or threads. The latter alternate with the set of plies of rib-like cellular structure 11. Note here that depth of the latter in the frame makes 0.4-0.6 of its width outside the frame. Circular plies arranged cross unidirectional bundles and/or threads can be made of woven and/or braided materials, e.g. glass, organic or carbon threads or combination thereof.

EFFECT: increased strength of shell.
