COMPOSITE LAMINATED PANEL WITH REDUCED ANGLE OF CROSS PLIES Russian patent published in 2018 - IPC B64C3/20 B64C3/26 B32B5/10 B32B5/12 B32B5/22

Abstract RU 2657619 C2

FIELD: aircraft.

SUBSTANCE: invention relates to aircraft and concerns the wings of composite laminated panels. Composite laminated panel comprises a first plurality of plies of reinforcing fibers oriented at an average angle α, and a second plurality of reinforcing fibers oriented at angles ±β relative to the main load direction. Moreover, α is 0 degrees relative to the main load direction, and β is between 15 and 35 degrees.

EFFECT: weight reduction of the wing skin is achieved without damaging the flexural strength, bending stiffness and failure resistance.
