Example Embodiment

[0023] Example 1

[0024] The preparation method of the long-fiber composite material of the present invention is that: at least two different long-fiber filaments are tightly woven to form a braid (which can be woven into a rod, tube, profile, plate or block ), wherein, when the two different long-fiber wires are both metal long-fiber wires, one of the metal long-fiber wires is required to constitute the metal fiber matrix of the braid, and the other one is Weave on the surface of the metal fiber matrix, and then realize the metallurgical bonding between the metal filaments, and finally the desired textured composite material can be manufactured (it can be rod, pipe, profile, plate or block material) ; When the two different filaments are metal filaments and non-metal filaments, the metal filaments are required to form the metal fiber matrix of the braid, and the non-metal filaments are woven in The surface of the metal fiber matrix, and then the metallurgical bonding between t...

Example Embodiment

[0026] Example 2

[0027] The difference from Embodiment 1 is that the metal wire in this embodiment is 20 steel wires.

Example Embodiment

[0028] Example 3

[0029] The difference from Embodiment 1 is that the metal wire in this embodiment is aluminum bronze, and when metallurgical bonding is achieved, it is heated to 880 degrees Celsius for two hours in a vacuum heating furnace.

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...
