Broad-width carbon-fiber knitting machine and method for producing carbon-fiber gridding cloth by using same

Abstract

The invention aims to study out special production equipment for knitting carbon-fiber gridding cloth through broad-width carbon fibers and a method for producing the carbon-fiber gridding cloth through the special production equipment. The invention has the technical scheme that a broad-width carbon-fiber knitting machine comprises a knitting-machine main body, a warp conveying device and a knitting table, wherein the warp conveying device is formed by a bottom supporting frame, a plurality of warp driving shafts and a plurality of traction driving shafts, a warp lifting and pulling device and an electric control box which are used for separating broad-width carbon-fiber tow bands up and down at intervals are also arranged on the knitting-machine main body, and a weft frame, a weft releasing device, a weft towing device, a weft cut-off device and a weft translating device are arranged on the knitting table. The invention also discloses the method for producing the carbon-fiber gridding cloth by using the broad-width carbon-fiber knitting machine. The invention has the beneficial effects that by adopting the knitting machine disclosed by the invention, the gridding-cloth knitting efficiency of the carbon-fiber tow bands after fiber expansion can be effectively improved, and the difficult problem that the carbon-fiber tow bands after fiber expansion need to be purely manually knitted is solved.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and relates to a special production equipment for wide-width carbon fiber weaving mesh carbon fiber cloth and a method for producing carbon fiber mesh cloth. Background technique [0002] Carbon fiber is a new material with excellent mechanical properties. It not only has the inherent characteristics of carbon materials, but also has the softness and processability of textile fibers. It is a new generation of reinforcing fibers. Compared with traditional glass fiber, the Young's modulus is more than three times; compared with Kevlar fiber, not only the Young's modulus is about two times, but also insoluble and non-swellable in organic solvents, acids and alkalis , Outstanding corrosion resistance. Its specific gravity is less than 1 / 4 of that of steel, and the tensile strength of carbon fiber resin composite materials produced is generally above 3500MPa, which is 7-9 times that of stee...
