One layer of the fabrics has the structure that parallel stretched carbon fiber yarn bundles are evenly arranged along the 0-degree direction, and the other layer of the fabrics has the structure that parallel stretched carbon fiber yarn bundles are evenly arranged along the 90-degree direction; the type of the carbon fiber yarn bundles is 3K-50k; the mass per unit area of the carbon fiber yarn bundles which are parallel stretched and evenly arranged along the 0-degree direction is larger than or equal to 150g/m<2> and is smaller than or equal to 1000g/m<2>, and the mass per unit area of the carbon fiber yarn bundles which are parallel stretched and evenly arranged along the 90-degree direction is larger than or equal to 75g/m<2> and is smaller than or equal to 400g/m<2>; and the pavement density of warp knitting wires is five wires in each inch, and the mass per unit area of the paved warp knitting wires is larger than or equal to 5g/m<2> and is smaller than or equal to 12g/m<2>. The biaxial carbon fiber warp knitting fabrics can make the best of the good performance of each part, so that the tensile strength, the sheering property and the tear resistance are improved; and due to the function of bound yarns, the friction force among the yarns is improved, and the performance between layers of the fabrics is enhanced, so that the application range of carbon fiber is enlarged.
Description
Technical field
The utility model relates to carbon fiber knitted composite material field, at length say be a kind of 0 the degree and an angle of 90 degrees twin shaft to carbon fiber warp-knitting cloth.
Background technology
As everyone knows, at present, how carbon fiber occurs with unidirectional carbon fiber dimension or carbon fiber woven fabric institutional framework in the application aspect many such as Aero-Space, war industry, sports equipment.Composite with the unidirectional carbon fiber dimension is made owing to the anisotropy of its structure, makes to be higher than perpendicular to the tensile property on the machine direction along the tensile property on the machine direction that range of application is limited to far away.In addition, unidirectional carbon fiber reinforced plastics thickness is little, in making large-scale thick product, and complicated operation.
Filling yarn in traditional carbon fiber woven fabric institutional framework is in case of bending, stretch after the bending of filling yarn elder generation during bearing load, product deformation is big, intensity is low, elastic modelling quantity is low, cutting performance, the interlayer poor performance, single yarn is stressed continuously when bearing tear edge, and tear resistance is poor, and fibre property can not be given full play in the carbon fiber woven fabric.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of 0 degree and an angle of 90 degrees twin shaft to carbon fiber warp-knitting cloth, give full play to the mechanical property of carbon fiber, this kind 0 degree and an angle of 90 degrees twin shaft can effectively design reinforced fiber in advance to carbon fiber warp-knitting cloth, utilize the premium properties of its each part, improve tensile property, improved cutting performance, strengthened tear resistance and interlayer performance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of 0 degree and an angle of 90 degrees twin shaft are to carbon fiber warp-knitting cloth, be provided with carbon fiber yarn bundle, it is characterized in that: by the two-layer parallel carbon fiber yarn Shu Zucheng that stretches, the two-layer parallel carbon fiber yarn Shu Youjing braided wire that stretches is through weaving together, wherein one deck is that the parallel carbon fiber yarn bundle that stretches is evenly arranged on the 0 degree angular direction, another layer is evenly arranged on an angle of 90 degrees direction for the parallel carbon fiber yarn bundle that stretches, carbon fiber yarn bundle model is 3K～50K, parallel stretch and evenly distributed 0 degree angular direction carbon fiber yarn bundle mass area ratio more than or equal to 150g/m
2, smaller or equal to 1000g/m
2, parallel stretch and evenly distributed an angle of 90 degrees direction carbon fiber yarn bundle mass area ratio more than or equal to 75g/m
2, smaller or equal to 400g/m
2, be five of per inch through the braided wire laying density, after the laying through the braided wire mass area ratio more than or equal to 5g/m
2, smaller or equal to 12g/m
2
The beneficial effects of the utility model are, can make full use of the premium properties of its each part, TENSILE STRENGTH, cutting performance, tear resistance are improved, because the effect of bondage yarn, improved the friction between yarn, strengthen the interlayer performance of fabric, thereby enlarged the range of application of carbon fiber.

Fig. 1 is a structural representation of the present utility model.
1. carbon fiber yarn bundles among Fig. 1,2. through braided wire, 3. carbon fiber yarn bundle.
The specific embodiment
In Fig. 1, the utility model is made up of parallel upper strata carbon fiber yarn bundle 1 that stretches and the parallel lower floor's carbon fiber yarn bundle 3 that stretches, the two-layer parallel carbon fiber yarn bundle that stretches by braided wire 2 through weaving together, wherein one deck is that the parallel carbon fiber yarn bundle 1 that stretches is evenly arranged on the 0 degree angular direction, another layer is evenly arranged on an angle of 90 degrees direction for the parallel carbon fiber yarn bundle 3 that stretches, carbon fiber yarn bundle model is that 3K～50K(is that every bundle carbon fiber yarn bundle 1 contains 3,000 to 50,000 carbon fiber wires), parallel stretch and evenly distributed 0 degree angular direction carbon fiber yarn bundle mass area ratio more than or equal to 150g/m
2, smaller or equal to 1000g/m
2, parallel stretch and evenly distributed an angle of 90 degrees direction carbon fiber yarn bundle mass area ratio more than or equal to 75g/m
2, smaller or equal to 400g/m
2, be five of per inch (i.e. 25. 4mm) through braided wire 2 laying density, after the laying through braided wire 2 mass area ratios more than or equal to 5g/m
2, smaller or equal to 12g/m
2, and do not contain any lubricant.
