Main problem of durability of lattice composite fuselage structure is decrease of strength properties of elements with unidirectional stacking (UD-ribs) because of impacts. Besides there are no reliable concepts of repairing UD-ribs. The results of investigation of damage parameters influence on strength of lattice fuselage and the results of evaluation of different repair variants are presented.
