Abstract

The invention discloses a carbon fiber rope and a manufacturing method thereof. The carbon fiber rope comprises a rope skin and a carbon fiber rope core, wherein the rope skin covers the outer part of the carbon fiber rope core; folded carbon fiber cloth is taken as the rope core, and is covered with the weaved rope skin made of other materials, so that the carbon fiber weaving is avoided; and the carbon fiber damage is greatly reduced. The rope has the characteristics of high roping strength, small fiber damage, simple technology and the like.

Description

A kind of carbon fiber rope and preparation method thereof

Technical field

The present invention relates to the rope field, specifically a kind of carbon fiber rope and preparation method thereof.

Background technology

Carbon fiber has high strength, high-modulus, performance such as high temperature resistant, corrosion-resistant, is a kind of chemical materials that has strong stretching resistance and fiber softening machinability two big features concurrently.Its density is less than 1/4 of steel, but tensile strength but is 7-9 times of steel, and tension elasticity also is higher than steel.But modulus of carbon fibres height, thread friction coefficient are big, performances such as poor, the easy brittle failure of bending property have also reduced its knitting property greatly, and then limited it in the rope making industry, the particularly application in the sennit, namely be not weave, owing to become rope to need numerous fiber, so also exist the problem of fiber alignment inequality, influenced rope intensity.

Summary of the invention

The objective of the invention is: a kind of effective, that fibre damage is low, one-tenth rope intensity is high carbon fiber rope and preparation method thereof that becomes to restrict is provided.

For achieving the above object, the technical solution used in the present invention is as follows:

A kind of carbon fiber rope comprises carbon fiber wire rope core and rope skin, and the braiding of rope skin is coated on the outside of carbon fiber wire rope core, and the carbon fiber wire rope core is the woven carbon fiber cloth after folding.

Described rope skin is chemical fibre class, natural fabric class, plastics class or high-performance fiber.

The warp thread of described woven carbon fiber cloth is carbon fiber, and weft yarn is a kind of of chemical fibre class, natural fabric class or plastics class yarn.

A kind of preparation method of carbon fiber rope, realize as follows:

1) carbon fiber lacks warp knit by woven mode and becomes woven carbon fiber cloth; Lacking the warp thread mode has two kinds, and a kind of is the equidistant warp thread that lacks; A kind of is to subtract apart from lacking warp thread from the centre to both sides etc.

2) woven carbon fiber cloth is folded into wire rope core from prolonging scarce warp thread position on one side successively.

3) use braiding machine that wire rope core is compiled suitcase and cover and form the carbon fiber rope, the weaving manner of braiding machine is a kind of in plain weave, the twill.

The invention has the beneficial effects as follows: as wire rope core, the outside is coated with the kernmantle skin of other materials, thereby has avoided the braiding of carbon fiber, greatly reduces the damage of carbon fiber with the carbon cloth after folding; In addition, utilize the high characteristics of the carbon cloth fiber alignment depth of parallelism, improved the arrangement uniformity of carbon fiber, and then improved one-tenth rope intensity.So, characteristics such as the present invention has into rope intensity height, fibre damage is little, technology is simple.

The specific embodiment

Describe the present invention below in conjunction with the drawings and specific embodiments:

Be illustrated in figure 1 as specific embodiments of the invention, be to be the schematic cross-section of the carbon fiber rope of wire rope core equidistantly to lack warp thread woven carbon fiber cloth, the carbon fiber rope comprises carbon fiber wire rope core 1 and

rope skin

2, and 2 braidings of rope skin are coated on the outside of described carbon fiber wire rope core 1.Carbon fiber wire rope core 1 is the woven carbon fiber cloth 3 after folding, and the warp thread of woven carbon fiber cloth 3 is carbon fiber, and weft yarn is a kind of of chemical fibre class, natural fabric class or plastics class yarn.Rope skin 2 is raw materials used to be chemical fibre class, natural fabric class, plastics class or high-performance fiber.

The preparation method of carbon fiber rope, realize as follows:

1) carbon fiber lacks warp knit by woven mode and becomes woven carbon fiber cloth 3; Wherein lacking the warp thread mode has two kinds, and a kind of is the equidistant warp thread that lacks; A kind of is to subtract apart from lacking warp thread from the centre to both sides etc.;

2) woven carbon fiber cloth 3 is folded into wire rope core 1 from prolonging scarce warp thread position on one side successively;

3) use braiding machine that wire rope core 1 is compiled suitcase and cover and form the carbon fiber rope, weaving manner is a kind of in plain weave, the twill.

Embodiment 1:

Fig. 1 is for being the schematic cross-section of the carbon fiber rope of wire rope core equidistantly to lack warp thread woven carbon fiber cloth, and Fig. 2 is the schematic diagram that equidistantly lacks warp thread woven carbon fiber cloth, and a kind of weaving of carbon fiber rope is as follows as shown in Figure 1, 2:

1) according to equidistantly lacking warp thread, adopts woven mode, be woven into woven carbon fiber cloth 3;

2) will equidistantly lack warp thread woven carbon fiber cloth, Yi Bian be folded into wire rope core 1 from prolonging scarce warp thread position successively;

3) the rope skin adopts the aramid fiber long filament, uses the high speed circular braiding, and wire rope core 1 is carried out twill weave, and rope skin 2 is coated on the outside of wire rope core 1.

Embodiment 2:

As shown in Figure 1, 2, a kind of weaving of carbon fiber rope is as follows:

3) the rope skin adopts polyester filament, uses the high speed circular braiding, and wire rope core 1 is carried out plain weave, and rope skin 2 is coated on the outside of wire rope core 1.
