Abstract
It the utility model is related to a kind of wind power generation blade new structure fabric.It is characterized in that warp direction spreads the roving fibers layer into agent structure, the reinforcing fibre silk into broadwise is spread in the second layer of fabric, the above-mentioned roving fibers layer of binding braiding is made by polyester hot melting fiber again, enhancement layer forms an overall structure, again by heater by fibrous layer of the fiber melting adhesion of polyester hot melting through broadwise, before product winding during form a constitutionally stable material after natural cooling.The utility model is a kind of structure that can control fabric very well, it is easy to can to need high intensity according to blade root during the big beam parts of leaf production and blade tip only needs the characteristic of the gradual transition of relatively low intensity to cut cloth when stepped cross is used not fall apart, simultaneously by heating fixed structure, make the good flatness of cloth mask body, Tension Evenness, improve fabric intensity and the process structure of modulus simultaneously, the own wt of the material is greatly reduced, so as to meet the requirement of high end composites fan blade.
Description
Technical field
The utility model belongs to technical field of novel materials, is related to a kind of industrial textile, more particularly to a kind of wind-force
Power generation blade new structure fabric.
Background technology
Not only development is quick in recent years for China's wind power industry, technology maturity more and more higher, power of motor also from
1.5MW almost all is upgraded to more than 2MW, and quickly develops the high-power blade profiles of more than 3MW, and the length of blade has reached 50-
80 meters, wind-power electricity generation power improves constantly, it is desirable to blade have it is stronger catch wind energy power, the material of blade is lighter, intensity
With rigidity superelevation, the ability that blade resists load is stronger, therefore the improvement on the process structure of composite material reinforcement body material
And upgrading, it is particularly important.
Utility model content
The purpose of this utility model is in order to solve the problems, such as that prior art is present, so as to provide a kind of wind power generation blade
With new structure fabric, there is excellent mechanical property and processing performance.
The technical solution adopted in the utility model is：A kind of wind power generation blade new structure fabric, it is characterised in that
Warp direction spreads the roving fibers layer into agent structure, and the reinforcing fibre silk into broadwise is spread in the second layer of fabric, then by polyester
Meldable fibre makees binding and weaves above-mentioned roving fibers layer, enhancement layer one overall structure of composition, then will be poly- by heater
Ester meldable fibre melts fibrous layer of the adhesion through broadwise, before product winding during that a structure is formed after natural cooling is steady
Fixed material.
The fiber of described roving fibers layer is the high performance fibers such as high-strength and high-modulus glass fibre.
Described reinforcing fibre silk uses 100TEX-200TEX specification glass fiber yarns.
40 grams of the fiber weight per unit area of described reinforcing fibre silk.
Described polyester hot melting fiber uses 70D fused yarns.
The density of described roving fibers layer is 1150-1200 grams of the fiber Unit Weight not less than 12 pieces/inch.
The utility model is a kind of structure that can control fabric very well, can be according to leaf when being easy to the big beam parts of leaf production
Root needs high intensity and blade tip only needs the characteristic of the gradual transition of relatively low intensity to cut cloth when stepped cross is used not dissipate
Frame, while by heating fixed structure, make the good flatness of cloth mask body, Tension Evenness, while improve fabric intensity
With the process structure of modulus, the own wt of the material is greatly reduced, so as to meet high end composites fan blade
It is required that.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, thin description is carried out to a kind of multiple layer inlaid thread stitch bonded fabrics of the utility model：
As shown in Figure 1：The utility model is using the alkali-free glass fibre epoxy yarn of 2400TEX high strength and modulus as warp
To (0 degree) fibrous layer 1, density is 12.5 pieces/inch, 1181 grams of fiber Unit Weight；Lower floor is with the medium-sized alkali-frees of 100tex
Glass fiber yarn is broadwise (90 degree) enhancement layer 2,40 grams of fiber weight per unit area；Again one is woven into through polyester hot melting fiber
Individual entirety simultaneously heats one constitutionally stable material of formation after adhesion cooling, and polyester hot melting fiber is 70D fused yarns.
The utility model is a kind of structure that can control fabric very well, can be according to leaf when being easy to the big beam parts of leaf production
Root needs high intensity and blade tip only needs the characteristic of the gradual transition of relatively low intensity to cut cloth when stepped cross is used not dissipate
Frame, while by heating fixed structure, make the good flatness of cloth mask body, Tension Evenness, while improve fabric intensity
With the process structure of modulus, the own wt of the material is greatly reduced, so as to meet high end composites fan blade
It is required that.
Listed above is only specific embodiment of the utility model, and the utility model is not limited to above embodiment,
There can also be many deformations.One of ordinary skill in the art directly can export or associate from the utility model disclosure
All deformations, be considered as the scope of protection of the utility model.
