Problems solved by technology

It can be seen from the above prior art that metallic glass fibers are prepared by melt spinning or aerosol technology, but when the metallic glass is subjected to tension, the main shear bands slip unhindered, causing the metallic glass fibers to soften and become unstable. , it is necessary to further improve the tensile toughness of the metal glass fiber to hinder the slippage of the main shear band

Abstract

The invention provides a preparation method of multifunctional metal / metallic glass blended fabric with enhanced stretching. The method includes the following steps that mother alloy powder obtained by preparing Pd powder, Cu powder, Ni power and P powder is smashed into pieces, the pieces are added into a graphene oxide water solution, the mixture is stirred to volatize solvent, then the mixtureis added into vacuum heating and solidifying equipment in batch, under the atmosphere of inertial gas, the metallic glass mixture to be subjected to graphene oxide modification is totally fused, andthen a spinning solution is obtained; the spinning solution is put into a melt spinning device, a supercooling liquid phase region of metallic glass is set to have a forming temperature, and a PdCuNiPmetallic glass fiber is obtained through pressurizing and extruding; one end of the PdCuNiP metallic glass fiber is connected with a rotating device, the other end of the PdCuNiP metallic glass fiberis put into a copper sulfate electrolyte to serve as a cathode, a copper plate is used as an anode, rotating for copper plating is performed, and then an enhanced-stretching metallic glass fiber wrapped with copper is obtained; the enhanced-stretching metallic glass fiber wrapped with copper and the metallic fiber are subjected to blending, and therefore the multifunctional metal / metallic glass blended fabric with enhanced stretching is prepared.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a preparation method of a stretch-reinforced multifunctional metal / metal glass blended fabric. Background technique [0002] Metallic glass, also known as amorphous alloy, is a new type of glass. It is formed by rapid solidification of crystals, so that the atoms are too late to return to the usual lattice structure and fixed, and the atoms are in a random and disordered arrangement. Different from the properties of traditional glass materials, metallic glass has some characteristics of glass, metal, solid and liquid. Under normal cooling conditions, the alloy melt always crystallizes quickly during the cooling process to form a solid with an amorphous structure. . Metallic glass has excellent mechanical, chemical and physical properties, such as super mechanical properties and resistance to strong acids and alkalis. It has a hardness close to that of ceram...
