Abstract

The utility model discloses a single axial warp braided fabric, which comprises a weft yarn layer, binding yarns, a mesh layer and a short cut fiber felt layer. The weft yarn layer consists of weft yarns arrayed in a zero-degree direction, the mesh layer consists of warp yarns and weft yarns, and the binding yarns positioned in the zero-degree direction sequentially tie, sew and braid the weft yarn layer, the mesh layer and the short cut fiber felt layer into a whole. The warp yarns, the weft yarns and short cut fibers are all glass fiber yarns, and the binding yarns are polyester yarns. The number of the weft yarns in the weft yarn layer is 2400tex with density of 468 per meter, the weight of meshes in unit area is 67 grams per square meter, the number of the short cut fibers is 2400tex, the weight of short cut fiber felts in unit area is 50 grams per square meter, and the number of the binding yarns is 8.3tex with density of 315 per meter and an upper wire ring density of 210 per meter. The single axial warp braided fabric is high in strength with precision of weight of the fabric in unit area up to 1250+/-3% grams per square meter, and can effectively meet the requirement of strength in some severe use environments and occasions with large stress.

Description

Single shaft is to tricot

Technical field

The utility model relates to a kind of tricot, particularly relates to a kind of single shaft of reinforcing materials such as wind power generation blade, naval vessels that is used for to tricot.

Background technology

At present, to tricot, weft layers that is made of the weft yarn arrangement of zero degree direction and the bundled yarn that spaced each weft yarn bondage loop bonding is become one constitute as the single shaft of reinforcing materials such as wind power generation blade, naval vessels.This fabric has good tensile and DIMENSIONAL STABILITY along lining yarn direction, but, the tension of this fabric, shearing resistance equal strength performance still can not satisfy the requirement of strength of abominable, the stressed big occasion of some environment for use in actual use, the for example instructions for use of the main force part of wind power generation blade girder, girder is when adopting this fabric as reinforcing material, cracking in use often appears, even fracture accident.In addition, as the wind power generation blade reinforcing material time,, require the unit are grammes per square metre of zero degree direction weft yarn to be accurate to 1123g/m corresponding to the wind power plant of certain power ², the grammes per square metre of fabric unit are is accurate to 1250 ± 3%g/m ², and the at present domestic and international same industry all can not reach this regulation requirement, consequently the blade of producing can't satisfy described wind power plant necessary requirement, even in use this generating equipment is caused damage.

The utility model content:

The technical problems to be solved in the utility model provides a kind of intensity height, and a kind of single shaft that can satisfy abominable, the stressed big occasion requirement of strength of some environment for use better is to tricot.

For solving the problems of the technologies described above, the utility model adopts so a kind of single shaft to tricot, it comprises weft layers and bundled yarn that the weft yarn arrangement by the zero degree direction constitutes, and this fabric also comprises the grid layer of cloth that is made of warp thread and weft yarn and piled up the staple fiber carpet veneer that constitutes by the staple fiber section; Described bundled yarn is positioned at the zero degree direction and described weft layers, grid layer of cloth and staple fiber carpet veneer bondage loop bonding is successively become one.

Staple fiber in warp thread in weft yarn in the described weft layers, the grid layer of cloth and weft yarn and the staple fiber carpet veneer is glass fiber yarn, and described bundled yarn is a Polyester Yarns.

As a kind of preferred implementation of the present utility model, number number of weft yarn is 2400tex in the described weft layers, and density is 468 pieces/meter; Number number of warp thread is 68tex in the described grid layer of cloth, and warp count is 250 pieces/meter, and number number of weft yarn is 300tex, and weft count is 166 pieces/meter; The short-and-medium number number of cutting fiber of described staple fiber carpet veneer is 2400tex, and the grammes per square metre of chopped mat unit are is 50g/m ²Number number of described bundled yarn is 8.3tex, and density is 315 pieces/meter, and the density of the coil on described bundled yarn is 210/meter.

After adopting such structure, because this fabric is formed by weft layers, grid layer of cloth and staple fiber carpet veneer bondage loop bonding successively, therefore, the tensile strength of this fabric, shearing strength and shock resistance equal strength performance are more good, can satisfy the requirement of strength of abominable, the stressed big use occasion of some environments for use better.In addition, in the utility model, because the weft yarn employing number of zero degree direction is 2400tex in the weft layers, density is 468 pieces/meter glass fiber yarn, and the fabric of producing like this can guarantee that zero degree direction weft yarn unit are grammes per square metre is accurate to 1123g/m ²Because warp thread employing number is 68tex in the described grid layer of cloth, density is 250 pieces/meter glass fiber yarn, and weft yarn employing number is 300tex, and density is 166 pieces/meter glass fiber yarn, and the unit are grammes per square metre of grid cloth can be accurate to 67g/m like this ²Because the short-and-medium number number of cutting fiber of described staple fiber carpet veneer is 2400tex, the grammes per square metre of chopped mat unit are is 50g/m ²Because described bundled yarn employing number is 8.3tex, and density is 315 pieces/meter glass fiber yarn, and the density of the coil on described bundled yarn is 210/meter, the unit are grammes per square metre of bundled yarn can be accurate to 10g/m so again ², therefore, the fabric of this structure has reached the desired standard grammes per square metre of certain power wind power plant 1250 ± 3%g/m ²Thereby, guaranteed the quality of wind power generation blade to satisfy its instructions for use.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is a kind of cross-sectional schematic of the utility model single shaft to tricot.

Fig. 2 is a kind of structural representation of the utility model single shaft bundled yarn in tricot.

The specific embodiment

Referring to a kind of single shaft shown in Fig. 1,2 to tricot, comprise weft layers 1 and bundled yarn 4 that the weft yarn arrangement by the zero degree direction constitutes, this fabric also comprises the grid layer of cloth 2 that is made of warp thread and weft yarn and is piled up the staple fiber carpet veneer 3 that constitutes by the staple fiber section; Described bundled yarn 4 is positioned at the zero degree direction and described weft layers 1, grid layer of cloth 2 and staple fiber carpet veneer 3 bondage loop bonding is successively become one.In the utility model, described grid layer of cloth 2 can be constituted or constitute by adhesive is bonding mutually through woven by warp thread and weft yarn.
