Ding Fu's little knowledge: the mystery of fiber metal laminate
Tips from Dingfu: The mystery of fiber metal laminates. Fibers can reinforce metal laminates. It is made by gluing two or more layers of metal sheets and reinforcing fibers sandwiched between the sheets using adhesives. Laminates, also known as fiber-metal bonded laminates.
The metal sheets used are mostly aluminum alloys, aluminum alloys, aluminum-copper alloys, aluminum-zinc alloys, titanium alloys, steel and other structural metals can also be used. The thickness of the metal sheets is generally 0.1 to 0.3mm, and the reinforcing fiber is Tagawa Aramid, The glass fiber or carbon fiber reinforced fiber is in the form of unidirectionally arranged weftless cloth or woven fabric or the glue curing agent used for chopped fiber, which can be thermosetting or thermoplastic. Fiber-reinforced metal laminate is a relatively new structural material, which has the characteristics of good fatigue resistance and damage resistance, good environmental and lightning resistance, damping and molding processability. The performance of fiber-reinforced metal laminates also highly depends on the material's sintering parameters, by changing the fiber resin system, the type and specifications of the metal sheet, the layup procedure, the fiber orientation, the surface preparation process and the degree of curing, stretching or rolling, etc. A wide variety of laminates can be manufactured.
Laminated metal composite materials are composed of two or more layers of different metals. The layers are perfectly combined with each other through rolling, extrusion, fusion, explosive welding, and brazing, and they are different from each other. The metal properties of each composition.
The effective elastic modulus or specific stiffness of the metal laminate not only depends on the elastic modulus, density and volume ratio of the metal components of the laminate, but also depends on the load mode and arrangement of the laminate structure.
In the case that the composite material is uniaxially loaded, that is, in any direction parallel to the laminate, the elastic behavior of the laminated metal composite material and the unidirectional fiber-reinforced composite material under the stress parallel to the fiber direction behave The elastic behavior is similar, and it is easy to estimate according to the mixing rule. However, for multilayer composite materials, only when the number of layers is large enough and the materials with different modulus are uniformly distributed in the thickness direction of the composite material, the calculated and actual values of the mixing rule under transverse bending or torsion load are the same. similar.
