Technical field
The utility model relates to a kind of industrial composite material for weaving, particularly relate to a kind of for the twin shaft on blade of wind-driven generator to strengthening fabric.
Background technology
Blade is that wind-driven generator catches wind energy most critical and most basic parts, and blade involves great expense, and accounts for 20%～30% of whole wind power generating set cost.The little operational efficiency that is conducive to improve blower fan of the mass density of blade, but wind power generating set will turn round under adverse circumstances usually for a long time, requires to have again enough fatigue strength and mechanical performance.For manufacturing and the operating cost that reduces generating set, require blade low cost of manufacture and easy for installation, the life-span long and the maintenance few, high-strength by the composite material light that glass fibre and thermoplastic resin form, corrosion resistance is good, designability is strong, is the preferred material of present large fan blade.
At present, the enhancing fabric on blade adopts the traditional woven things such as glass fibre woven roving, twill usually, and woven fabric intensity is low, modulus is not high, and a large amount of yarns often occurs in process come off, waste greatlyr, be unfavorable for using in large medium size wind generator.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provides that a kind of intensity is high, non-deformability is strong, and the used for blades of wind driven generator twin shaft that is conducive to use in large medium size wind generator is to strengthening fabric.
for solving the problems of the technologies described above, the utility model adopts a kind of like this used for blades of wind driven generator twin shaft to strengthening fabric, this fabric is by the first weft layers that is arranged in order from top to bottom, the second weft layers, thread layer and the 3rd weft layers and bundled yarn consist of, described the first weft layers is made of the weft yarn arrangement of some positive 30 degree directions, described the second weft layers is made of the weft yarn arrangement of some negative 30 degree directions, described thread layer is arranged by the warp thread of some zero degree directions and is consisted of, described the 3rd weft layers is made of the weft yarn arrangement of some 90 degree directions, described bundled yarn is positioned at the zero degree direction, this bundled yarn is with described the first weft layers, the second weft layers, thread layer and the 3rd weft layers bondage are woven into and are integrated.
As a kind of preferred embodiment of the present utility model, number number average of the weft yarn of described positive and negative 30 degree directions is 600 tex, and thread density is 670 pieces/meter; Number number average of the weft yarn of the warp thread of described zero degree direction and 90 degree directions is 68 tex, and thread density is 28 pieces/meter; Number number of described bundled yarn is 8.3 tex, and thread density is 240 pieces/meter, and the density of the coil on bundled yarn is 350/meter.
In the utility model, the weft yarn of described positive and negative 30 degree directions is fibre glass roving, and the weft yarn of the warp thread of described zero degree direction and 90 degree directions is glass fiber spun yarn, and described bundled yarn is Polyester Yarns.
After adopting such structure, the utlity model has following beneficial effect:
due to enhancing fabric of the present utility model by first, the second weft layers, thread layer and the 3rd weft layers and bundled yarn consist of, the first weft layers is made of the weft yarn arrangement of positive 30 degree directions, the second weft layers is made of the weft yarn arrangement of negative 30 degree directions, thread layer is arranged by the warp thread of zero degree direction and is consisted of, the 3rd weft layers is made of the weft yarn arrangement of 90 degree directions, bundled yarn is with first, the second weft layers, thread layer and the 3rd weft layers bondage are woven into and are integrated, therefore, the enhancing fabric of this structure just has, the weft yarn of negative 30 degree directions, and the warp thread and 90 with the zero degree direction is spent the weft yarn of directions as fixed yarn, greatly strengthened the non-deformability of fabric, in use greatly reduced the distortion of blade, and should strengthen the tension of fabric, shearing strength is high, guaranteed the quality of blade, can satisfy well the instructions for use in large medium size wind generator.
Adopt 600 tex yarns due to enhancing fabric of the present utility model at the weft yarn of positive and negative 30 degree directions, density adopts 670 pieces/meter, and the unit are grammes per square metre of first, second weft layers is 401g/ m like this
2The weft yarn of the warp thread of zero degree direction and 90 degree directions adopts 68 tex yarns, and density adopts 28 pieces/meter, and the unit are grammes per square metre of thread layer and the 3rd weft layers is 1.9g/ m like this
2Number number of bundled yarn is 8.3 tex, and density is 240 pieces/meter, and loop density is 350/meter, and its unit are grammes per square metre is 8.3g/ m
2, the total grammes per square metre of enhancing fabric of producing like this is 814 g/ m
2, therefore, the non-deformability of the enhancing fabric of this structure is stronger, and intensity is higher, more is conducive to use in large medium size wind generator.
