Metal-plastic laminate, especially for use in aircraft fuselage production, comprises metal sheets adhesively bonded with a plastic interlayer containing basalt filaments

摘要

Metal-plastic laminate in which the adhesive plastic interlayer contains basalt filaments with an elastic modulus of 90-120 GPa, a silicon dioxide content of 35-55 (preferably 47-50) wt%, an aluminum oxide content of 10-25 (preferably 15-18) wt% and a magnesium oxide content of 3-10 (preferably 5-7) wt%, and the metal has a tensile strength of more than 0.2 GPa. A laminate of at least two metal sheets, each with a thickness of less than 1.5 (preferably 0.1-0.8) mm, with an adhesively-bonded plastic layer between the sheets containing 35-75 vol% of basalt filaments with an elastic modulus of more than 50 GPa. The basalt filaments show an elastic modulus of 90-120 GPa, an SiO 2 content of 35-55 (preferably 47-50) wt%, an Al 2O 3 content of 10-25 (preferably 15-18) wt% and an MgO content of 3-10 (preferably 5-7) wt%, and the metal sheets consist of material with a tensile strength of more than 0.2 GPa. An independent claim is also included for an aircraft fuselage in which the outer shell consists of this laminate.
