Abstract
The utility model relates to plus or minus 45DEG dual-axial carbon fiber warp knitted fabric, which belongs to the field of carbon fiber composite materials. In one layer, parallel straightened carbon fiber yarn bundles are uniformly arranged in the direction of plus 45DEG, in the other layer, parallel straightened carbon fiber yarn bundles are uniformly arranged in the direction of plus 45DEG,, the model of carbon fiber yarn bundles is 3K to 50K, in each layer, the mass per unit of the parallel straightened and uniformly arranged carbon fiber yarn bundles is larger than or equal to 75g/m2 and smaller than or equal to 400g/cm2, the laying density of the warp knitted threads is 5/inch, and after laying, the mass per unit of the warp knitted threads is larger than or equal to 5g/m2 and smaller than or equal to 12g/cm2. The plus or minus 45DEG dual-axial carbon fiber warp knitted fabric takes full advantages of the excellent properties of the components thereof to improve tensile strength, shearing performance and tear resistance, and due to the action of binder yarn, the friction force among yarns is increased, and the interlayer performance of the fabric is improved, thereby enlarging the application range of carbon fibers.
Description
Technical field
The utility model relates to carbon fiber knitted composite material field, at length say it is a kind of ± and the miter angle twin shaft is 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 ± miter angle twin shaft is to carbon fiber warp-knitting cloth, give full play to the mechanical property of carbon fiber, this kind ± miter angle 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 ± miter angle twin shaft is 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 be the parallel carbon fiber yarn bundle that stretches be evenly arranged in+the miter angle direction on, another layer be evenly arranged in for the parallel carbon fiber yarn bundle that stretches-the miter angle direction on, carbon fiber yarn bundle model is 3K～50K, every layer parallel stretch and evenly distributed 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 utility model also can be realized by following measure: be equipped with 0 degree angle Skeletal yarn between the two-layer parallel carbon fiber yarn bundle that stretches.
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.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
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 be the parallel carbon fiber yarn bundle 1 that stretches be evenly arranged in+the miter angle direction on, another layer be evenly arranged in for the parallel carbon fiber yarn bundle 3 that stretches-the miter angle direction on, 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), every layer parallel stretch and evenly distributed 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.
Can be equipped with 0 degree angle Skeletal yarn between the parallel upper strata carbon fiber yarn bundle 1 that stretches of the utility model and the parallel lower floor's carbon fiber yarn bundle 3 that stretches.
