<p>The invention relates to a fiber-metal laminate comprising mutually bonded fiber-reinforced composite layers and metal sheets, wherein the fiber and metal properties satisfy the following relationships simultaneously: (1) epsilonfibre tension>Ksf*sigmatu/(1.5*Et metal), (2) Efibre tension>Kstiff*Et metal, (3) epsilonfibre compression>ksf*sigmatu/(1.5*Klf*Et metal) wherein the strain concentration factor Ksf, stiffness factor Kstiff and the load factor Klf satisfy (4) 2.75@Ksf<5.7, (5) Kstiff>=1.28, (6) 1.5@Klf@3.5 and sigmatu=ultimate tensile strength of the metal, Et metal=tensile Young's modulus of the metal, epsilonfibre tension=elastic tensile strain of the fiber, Efibre tension=tensile elastic modulus of the fibre, epsilonfibre compression=elastic compression strain of the fiber. The fiber-metal laminate according to the invention shows an unprecedented combination of toughness and tensile strength. The invention further relates to an assembly of the fiber-metal laminate and a further element, bonded to the fiber-metal laminate by a bonding layer, comprising an adhesive and/or a fiber-reinforced composite.</p> |
