Description
Technical field
The present invention relates to a kind of fabric strengthening wind electricity blade performance and production method thereof.
Background technology
In the structure of wind electricity blade, the root of blade plays and connects the effect that blade reverses with wheel hub, to requirement of strength
Very big, so in the design of root of blade, the number of plies generally laying fabric is the most, this fabric primary structure is ground floor:
90 ° of yarns, second, third layer: ± 25 °～75 °.By 90 °, as a example by ± 45 ° of fabrics, this conventional kind fabric mode of production is for making
Use multi-shaft warp knitting equipment, the fabric of three angles is laid on weft yarn conveyer belt through paving Weft handling device simultaneously, then passes through chain
Bar drives to woven extent, is got up by bundled yarn binding braiding by establishment region, and this fabric, between yarn and yarn, layer
And the most closely knit between layer, blade root easily occurs when producing irrigating impermeable, the situation of perfusion difficulty, is unfavorable for yarn and resin
In conjunction with, final Blade Properties is impacted.
Summary of the invention
First purpose of the present invention is to provide a kind of fabric that can strengthen wind electricity blade performance.
The technical scheme realizing first purpose of the present invention is a kind of fabric strengthening wind electricity blade performance, including 90 ° of yarns
Line layer ,+N ° of thread layers ,-N ° of thread layers, the first bundled yarn and the second bundled yarn；Described+N ° of thread layers and-N ° of thread layers are by the
One bundled yarn is bundled into bi-axial fabric；Described bi-axial fabric and 90 ° of thread layers are bundled into polyaxial knitting by the second bundled yarn
Thing；The width often restrainting yarn of described 90 ° of thread layers is equal to the binding spacing of the second bundled yarn；Described 90 ° of thread layers adjacent
Perfusion channel is formed between yarn strand and between bi-axial fabric and 90 ° of thread layers；N is natural number.
The span of described N is: 25～75.
Described first bundled yarn and the second bundled yarn are 0 ° of yarn.
Described first bundled yarn and the second bundled yarn location overlap.
Second object of the present invention is to provide the production method of a kind of fabric strengthening wind electricity blade performance.
The technical scheme realizing second purpose of the present invention is the production method of a kind of fabric strengthening wind electricity blade performance,
Comprise the following steps:
Step one: lay ± N ° of yarn；；N is natural number；
Step 2: be tied to bi-axial fabric in the first knitting zone braiding by the first bundled yarn；
Step 3: by bi-axial fabric rolling, cutting；
Step 4: traction unreels, releases bi-axial fabric；
Step 5: yarn wide for a branch of bundle is directly laid on bi-axial fabric along 90 ° of directions；
Step 6: be tied to multi-axial fabric by the second bundled yarn in the second knitting zone braiding, the bundle of the second bundled yarn
Tie up the spacing width equal to a branch of 90 ° of yarns.
The span of described N is: 25～75.
Described first bundled yarn and the second bundled yarn are 0 ° of yarn.
In described step 6, the binding position of the second bundled yarn and the binding location overlap of the first bundled yarn.
In described step one, polyaxial weft weaving machine is used to carry out ± the lay of N ° of yarn；In described step 2, use multiaxis
The binding of the first bundled yarn is carried out to headstock；In described step 5, biaxially weft weaving machine is used to carry out the lay of 90 ° of yarns；Institute
State in step 6, use biaxially wagon box to carry out the binding of the second bundled yarn.
Have employed technique scheme, the present invention has a following positive effect: the fabric of (1) present invention ± angle
Yarn and the yarn of 90 ° between, namely owing to being through twice braiding between bi-axial fabric and 90 ° of yarns, exist certain
Gap, formed perfusion channel, when blade form, between gap import resin more, accelerate the time of perfusion,
It is more conducive to the combination of yarn and resin, enhances the fatigue behaviour of blade.
(2), in existing polyaxial technique, the yarn of 90 ° does not have relative independence, in order to enable during braiding
Enough disposable braidings, needing broadens 90 ° of Yarn twistings the most closely tiles, and yarn becomes a plane, no longer has substantially
Border, 90 ° of originally the most a branch of yarns can be isolated by bundled yarn when binding, the technique of the present invention, due to the yarn of ± angle
Line passes through and once weaves, and is provided with relative stability, and 90 ° of yarns can need not twisting tiling, and direct a branch of bundle is put
Up, binding spacing is equal to often restraint the width of yarn, and the thickness of every bunch determines according to the grammes per square metre of Fabric Design, it is not necessary to right
The yarn of 90 ° is interleaved, so gem-pure perfusion channel can be formed between the yarn strand of 90 °, advantageously in
The perfusion of resin, promotes the performance of fabric.
(3) weaving method of the present invention coordinates the structure of fabric of the present invention, and by twice braiding, twice rolling completes, work
Skill is the clearest, workable.
