FIELD: aircraft industry. ^ SUBSTANCE: layered panel comprises at least two interconnected stacks of metallic layers and plastic layers reinforced with fibers. The stacks have intermediate section `at which at least one of the internal layers is discontinuous. All other layers including outer metallic layers are continuous. Within the material, one stack of layered composition is smoothly goes into the other without onset of stress concentration. ^ EFFECT: enhanced strength. ^ 14 cl, 7 dwg |
