Description

Invisible hollow microsphere composite material
Technical Field
The invention belongs to the field of new materials, and particularly relates to a stealth hollow microsphere composite material.
Background
At present, stealth materials can be divided into two categories, namely stealth coating materials and stealth structure materials according to material purposes. The stealth coating material has low strength and poor bearing capacity, and cannot be used for a main bearing structure or a secondary bearing structure. The stealth structure material has good bearing capacity, but generally has higher density, and has poor applicability in the fields of aviation, aerospace, ocean and the like which have requirements on the density of the material.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provides a stealth cenosphere composite material.
The purpose of the invention can be realized by the following technical scheme: the stealth hollow microsphere composite material is characterized by comprising hollow microspheres and a matrix phase, wherein a stealth layer is arranged on the surfaces of the hollow microspheres, the stealth layer is made of a stealth material, and the hollow microspheres are filled in the matrix phase.
Preferably, the hollow microspheres are glass hollow microspheres and/or ceramic hollow microspheres.
Preferably, the matrix phase is an epoxy resin.
Preferably, the stealth material is selected from one of a nano metal material, a metal oxide material and a non-metal stealth material.
Preferably, the stealth layer is made of one of metal powder, ferrite, nickel oxide, carbon fiber and graphene.
Preferably, the stealth layer is formed on the surface of the hollow microsphere by one of electroplating, chemical plating and sol-gel method.
Preferably, the stealth hollow microsphere composite material forms a stealth hollow microsphere composite layer, fiber reinforced composite layers are arranged on two sides of the stealth hollow microsphere composite layer and made of fiber reinforced composite materials, and the stealth hollow microsphere composite layer and the two fiber reinforced composite layers form a sandwich structure. The middle part is a stealth hollow microsphere composite layer made of a stealth hollow microsphere composite material, and the two sides are fiber reinforced composite layers made of fiber reinforced composite materials, so that a sandwich structure is formed, and the stealth hollow microsphere composite material is wrapped inside the structure and is prevented from being influenced by external adverse environmental factors.
The working principle of the invention is as follows: the hollow microspheres have the diameter of dozens of microns to dozens of microns, large specific surface energy and high compressive strength, and the density of the hollow glass microspheres with the hollowness of more than 90 percent is less than 0.5g/cm for example3The highest compression strength can reach 200 MPa. The stealth layer is plated on the surfaces of the hollow microspheres by adopting a corresponding process, so that the hollow microsphere composite material has stealth capability on the basis of not obviously reducing the mechanical property of the hollow microsphere composite material. Thereby obtaining the hollow microsphere composite material with small density, high strength, strong bearing capacity and stealth function. The hollow microspheres plated with the stealth layer are filled in polymer matrixes such as epoxy resin and the like, so that the hollow microspheres with the compressive strength of more than 100MPa and the density of less than 0.7g/cm can be obtained3The hollow microsphere composite material.
Compared with the prior art, the invention has the following advantages:
1. compared with the common stealth material, the obtained stealth hollow microsphere composite material has the characteristics of low density, high strength and strong bearing capacity.
2. Compared with the traditional stealth material (the traditional stealth material is a coating or has low strength, and cannot be combined with the fiber reinforced composite material to form a sandwich structure), the stealth hollow microsphere composite material obtained by the invention can be combined with the fiber reinforced composite material to form a sandwich structure, and the stealth hollow microsphere composite material is wrapped in the structure to be free from the influence of external adverse environmental factors.
3. Compared with the coating stealth material with millimeter-scale thickness, the obtained stealth hollow microsphere composite material can be wrapped in the structure, the designability is strong, the thickness can be designed to centimeter-scale, and the improvement of stealth performance is facilitated.
