Abstract
The invention discloses a production method of a high-performance fiber pre-shaping single-direction belt, wherein the production method includes following steps: 1) preparing carbon fiber precursor; 2) performing fiber expansion to the carbon fiber precursor; 3) pre-heating the carbon fiber after fiber expansion; 4) spraying a shaping agent on the surface of the carbon fiber; 5) secondary heating the carbon fiber on which the shaping agent is sprayed; 6) cooling the carbon fiber; 7) laminating the carbon fiber; and 8) reeling the carbon fiber onto a reel head with centrifugal paper. By means of the shaping agent uniformly sprayed on the surface of the carbon fiber, the fiber has a certain stiffness degree, so that the single-direction belt has a pre-shaping effect and is free of an arch defect on the fiber during production. The production method fundamentally ensures surface flatness of the single-direction cloth, reduces production steps of the single-direction cloth, and increases weaving efficiency of the single-direction cloth.
Description
Technical field
This practicality invention relates to the production method of high-performance fiber pre-setting one-way tape.
Background technology
Wind energy, as a kind of clean regenerative resource, is more and more subject to the attention of countries in the world.The wind energy amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 × 10^9MW, and wherein available wind energy is 2 × 10^7MW, and than the water energy total amount that the earth can develop also large 10 times, but along with the expansion in city, wind resource is also reducing gradually.
The fan blade of wind-power electricity generation along with the increase of megawatt number and the minimizing of wind resource increasing, the weight of blade becomes a key issue, while how reducing weight again proof strength can up to standard become a task of top priority.The center of gravity of blade is crossbeam, if can alleviate the weight of crossbeam, that has considerable change to the function of entirety.So the selection of crossbeam becomes the method for a solution relatively efficiently, glass-fiber-fabric common is at present the original selection of blade girder, but the properties of glass-fiber-fabric finished product is limited by the performance of glass fibre, modulus is less than normal, easily fracture, therefore can not meet frivolous, the high windproof requirement day by day improved.
Therefore applicant considers the mode using the fine glass shuffling of carbon, utilizes the high-modulus of carbon fiber to improve to the modulus meeting conjugate fiber fabric unit, to reach the light and strong requirement of crossbeam.But because the manufacturing technique requirent of pure glass and the fine one-way fabric of pure carbon is inconsistent, the two tension force own is also inconsistent, if cloth cover can be caused uneven by the production method of pure glass, some little arch camber slightly, the part performance made after making later stage client use is had a greatly reduced quality.Therefore applicant considers that first carbon fibre being made pre-setting one-way tape makes yarn keep smooth, reduces the negative effect that two kinds of fiber different specialities cause.
practical summary of the invention
The object of this practicality invention is to provide the production method of high-performance fiber pre-setting one-way tape, makes unidirectional with pre-setting effect, ensures the cloth surface evenness of unidirectional cloth.
The technical scheme realizing this practical goal of the invention is: the production method of high-performance fiber pre-setting one-way tape, comprises the following steps:

Have employed technique scheme, this practicality invention has following beneficial effect: (1) the present invention is by spraying setting agent equably at fiber surface, fiber is made to have certain stiffness, thus make unidirectional with pre-setting effect, the phenomenon making one-way tape there will not be fiber in process of production to arch upward, thus in root, ensure that the cloth surface evenness of unidirectional cloth, decrease the production stage of unidirectional cloth, improve the efficiency of unidirectional cloth braiding.
(2) the present invention preheats fiber, makes setting agent after being sprayed on fiber, can faster with fiber fusion.
(3) the present invention carries out post bake to the carbon fiber spraying setting agent, and setting agent can be made really to be blended in fiber, thus obtains perfect pre-setting one-way tape.
Detailed description of the invention
(embodiment 1)
The production method of the high-performance fiber pre-setting one-way tape of the present embodiment, comprises the following steps:
1., carbon fibre precursor is prepared.
2., exhibition is carried out to carbon fibre precursor fine.
3. the carbon fiber after exhibition fibre, is preheated, temperature is 30 DEG C ~ 50 DEG C, and mode of heating is that continuity moves normal heating (namely heater is fixed, and fiber moves), pre-warmed object makes setting agent after being sprayed on fiber, can faster with fiber fusion.
4., at carbon fiber surface spray setting agent, setting agent is epoxies setting agent or phenolic setting agent.
5., post bake is carried out to the carbon fiber spraying setting agent, heating-up temperature is 70 DEG C ~ 100 DEG C, mode of heating is that continuity moves normal heating (namely heater is fixed, fiber moves), the object of post bake makes fiber surface have certain temperature, thus allow setting agent really be blended in fiber, finally obtain perfect pre-setting one-way tape.
6., cool carbon fiber, cooling is adopted as solution cooling method.
7., laminated carbon-fibre, lamination adopt roll lamination.
8., coordinate centrifugal paper by coiled hair on carbon fibre winding.
What first will make when producing carbon fiber unidirectional cloth is make coiled hair, and the unidirectional cloth makeing certain fabric width needs several even tens coiled hairs, incomparable inconsistent due to the tension force of unidirectional fibre on each coiled hair, therefore cause the out-of-flatness of cloth cover in the inconsistent meeting doing Bu Shiyin tension force, now just need manually to come manually to adjust.
Produce by the production method of the present embodiment the pre-setting unidirectional fibre obtained and then solve this problem well, setting agent makes fiber have certain stiffness, there will not be arching upward of fiber in process of production, thus in root, ensure that the cloth surface evenness of unidirectional cloth, decrease the production stage of unidirectional cloth, improve the efficiency of unidirectional cloth braiding.
Above-described specific embodiment; object, technical scheme and beneficial effect that this practicality is invented are further described; be understood that; the foregoing is only the specific embodiment of this practicality invention; be not limited to this practicality invention; within all spirit in this practicality invention and principle, any amendment made, equivalent replacements, improvement etc., all should be included within protection domain that this practicality invents.
