FIELD: aviation.

SUBSTANCE: panel contains a skin with a smooth flat outer surface of geometric shape and a framework attached to it in the form of a system of criss-crossing ribs consisting of layers fastened with a polymeric binder, unidirectional high-strength and/or high-modulus yarns and/or fabrics. And in the space between the ribs porous material is located, with formation with the latter of equidistantly outer surface of the skin of a continuous smooth surface on which strips of woven material, with perpendicular to the surface flanges, that are fastened with it by adhesive or polymeric binder in the longitudinal direction of panel between the longitudinal ribs impregnated with the binder, space between which is filled with an impregnated polymeric binder, oriented in the direction of strips arrangement, unidirectional reinforcing material with formation of power stringers coated by woven fabric material, constituting integrally with framework longitudinal ribs.

EFFECT: increasing the strength and reliability of the skin connection with power stringer, simplifying the manufacturing.
