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.

Description

technical field [0001] The invention discloses a fiber / metal layer structure composite material and a preparation method thereof, relates to the manufacturing technology of functional composite materials, and belongs to the field of material science. Background technique [0002] With the development of science and technology in the fields of aviation and aerospace, rockets, manned spacecraft, space stations and other spacecraft have been successfully launched one after another, which put forward new requirements for the properties of materials used such as lightweight, high temperature resistance, and easy repair. Composite materials are widely used in aviation and aerospace fields because of their advantages such as high specific strength and good fatigue performance. Unfortunately, under complex working conditions such as meteorite impacts and ion radiation in outer space, the composite materials used in spacecraft will be damaged. The occurrence of related material damag...
