The possibility of application fibre metal laminates for the elements of fuselage skin

High potential for the application in the elements of construction of mechanical engineering has layered composites on a base of thin sheets from aluminium alloys reinforced with different nonme-tallic fibers. The unique combination of FML characteristics (high crack resistance and specific static strength, good fatigue, corrosion, impact performances, fire resistance) makes this material as the advanced one for future generation of aviation structures as compared to monolithic aluminium sheets. The light (d=2.59 g/cm3) and high-modulus (E=80 GPa) Al-Li alloy 1441 is high workable in terms of cold rolling. The use of clad and unclad thin (down to 0.3 mm) 1441T11 alloy sheets in FML composition instead of sheets from traditional aluminium alloys of 2xxx and 7xxx series to reduce density and to enhance modulus of FML. As a result weight affectivity and stiffness of struc-tures increase.
