Fiber/metal layer structure composite and preparation method thereof

Abstract

The invention discloses a fiber/metal layer structure composite and a preparation method thereof, and relates to the field of manufacturing of functional composites. The fiber/metal layer structure composite comprises alternate fiber resin layers and metal layers; rubber layers can be further added; repairing agent microcapsules and a catalyst are added in resin; and micron strength enhanced particles can be further added. The preparation method comprises the steps of wetting fibers through resin, so as to prepare the fiber resin layers; carrying out surface treatment on metal sheets, so as to prepare the metal layers; alternately laying the fiber resin layers and the metal layers in a mold cavity; and carrying out heating, pressurization and curing treatment on the layer structures in the mold cavity. According to the fiber/metal layer structure composite, advantages of the fiber resin composite, metals and rubber are combined, the composite has relatively high designability, and the designed material is a functional composite with the prominent characteristics of high specific strength, fatigue resistance, corrosion resistance, high damping, and the like, and meets the urgent requirements of fields like aerospace, national defense, rail transit and automobiles on new materials to a certain extent.
