Method for preparing long-fiber composite material

Abstract

The invention discloses a method for preparing a long-fiber composite material. The method comprises the following steps: tightly weaving a metal long-fiber yarn material and a nonmetallic long-fiber yarn material to form a fabric body, allowing the metal long-fiber yarn material to form a metal fiber matrix of the fabric body, and weaving the nonmetallic long-fiber yarn material on the surface of the metal fiber matrix; and realizing metallurgical bonding between the metal long-fiber yarn materials, and finally manufacturing, thereby obtaining the woven composite material of which the needed matrix is a metal long fiber and the surface is nonmetallic long fiber. Because the composite material is obtained by weaving fibers, the metal long-fiber yarn material and the nonmetallic long-fiber yarn material do not have a clear interface, are constrained, restricted and included with each other and are firmly and reliably bound. The method disclosed by the invention is simple in process steps, convenient to operate, easy to implement, relatively low in production cost, wide in application range and good in market prospects and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a preparation method of long fiber composite material. Background technique [0002] The application number is 201410225398.9 invention patent discloses a manufacturing method of metal materials with long fiber texture structure. Firstly, metal long fiber wires are tightly braided to form a braid, and then the voids in the braid are eliminated by plastic processing, and the wires are made The metallurgical combination is realized between them, and finally the required dense metal material with long fiber texture structure is obtained, that is, the non-porous metal material. The metal material with long fiber texture structure is manufactured. The fiber texture is continuous and has the high Excellent tensile strength and high fatigue strength properties, while having the stiffness of conventional volume materials, it can be processed into mechanical parts l...

Problems solved by technology

However, when the material needs to meet the performance of wear resistance, friction reduction and corrosion resistance at the same time, since the raw materials used in the above two patent methods are metal fibers, the materials prepared by them are limited to a certain extent.
