FIELD: machine building. ^ SUBSTANCE: net-like shell is formed with layers of systems of crossing, spiral, lengthwise and circular tapes out of unidirectional threads. Also the layers repeat thickness of the shell wall. Threads of the tapes are bound with polymer binding and create spiral, circular, lengthwise and additional ribs. Additional ribs are oriented lengthwise. Also additional ribs are shorter, than length of generatrix, and are non-uniformly distributed along length and perimetre. ^ EFFECT: reduced weight of net-like shell. ^ 3 cl, 2 dwg |
