摘要： Described is a laminate, including a stack of mutually bonded adhesive layers and metal sheets. The laminate includes abutting and/or overlapping metal sheet edges that extend along a length direction within a splicing region. A splice strap is connected to the laminate at an outer surface of the laminate across said splicing region. The splice strap includes one layer of fiber-reinforced adhesive or of metal sheet, or stacked layers of fiber-reinforced adhesive and/or metal sheets. A widest splice strap layer is connected to the laminate over a transverse distance of at least 5 times the widest strap layer thickness, and the widest strap layer has a lower bending stiffness than the bending stiffness of one of the spliced metal sheets.

摘要： Disclosed is a laminate including a first metal sheet and an adhesive layer bonded to the first metal sheet, in which the following relationship applies: 1≦(Emetal*tmetal)/(Eadh*tadh)≦15 (1), where Emetal=tensile Young's modulus of the first metal sheet, tmetal=thickness of the first metal sheet, Eadh=tensile Young's modulus of the adhesive layer, and t=thickness of the adhesive layer. The adhesive layer may include reinforcing fibers. The laminate may be used for providing a fatigue resistant structure, such as an aerospace structure, and shows a high crack growth resistance, in particular near edges of the structure.

摘要： Described is laminate of a stack of mutually bonded adhesive layers and metal layers. An outer metal layer has spliced metal sheets having overlapping end parts and/or abutting metal sheet edges extending in a first and a different second planar direction of the laminate to define first and second splice lines. Connected to an outer surface are first and second splice straps covering the first and second splice lines. A lateral edge part of each splice strap has a lower bending stiffness than the bending stiffness of the outer metal layer sheets, the edge part being defined as extending from an outer lateral edge of a splice strap over a lateral distance of at least 5 times the edge part average thickness. The laminate may be used for making large structural components, such as a wing or fuselage of an aircraft.
