The triaxial carbon fiber warp knitted fabric comprises three layers of parallely extending carbon fiber yarn bundles; the three layers of the parallely extending carbon fiber yarn bundles are knitted together through warp knitted yarns; the parallely extending carbon fiber yarn bundles at the upper layer are uniformly distributed in the direction of 0-degree angle; the parallely extending carbon fiber yarn bundles at the lower layer are uniformly distributed in the direction of negative 45-degree angle; the parallely extending carbon fiber yarn bundles at the middle layer are uniformly distributed in the direction of positive 45-degree angle; the models of the carbon fiber yarn bundles are 3K to 50K; the mass per unit area of the parallely extending carbon fiber yarn bundles in the 0-degree direction angle is larger than or equal to 150 g/m<2> and smaller than or equal to 1000g/m2; the mass per unit area of the parallely extending carbon fiber yarn bundles in the 0-degree direction in the directions of positive/negative 45-degree angles is larger than or equal to 75g/m2 and smaller than and equal to 400g/m2; the laying density of the warp knitted yarns is five yarns per inch; and the mass per unit area of the laid warp knitted yarns is larger than or equal to 5g/m2 and smaller than or equal to 12g/m2.
Description
Technical field
The utility model relates to carbon fiber knitted composite material field, at length says it is a kind of three axial carbon fibres warp knitting cloths.
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 three axial carbon fibres warp knitting cloths, give full play to the mechanical property of carbon fiber, this kind three axial carbon fibres warp knitting cloths can effectively design reinforced fiber in advance, 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 three axial carbon fibres warp knitting cloths, be provided with carbon fiber yarn bundle, it is characterized in that: by three layers of parallel carbon fiber yarn Shu Zucheng that stretches, three layers of parallel carbon fiber yarn Shu Youjing braided wire that stretches are through weaving together, it is evenly arranged on the 0 degree angular direction for the parallel carbon fiber yarn bundle that stretches at the middle and upper levels, lower floor be the parallel carbon fiber yarn bundle that stretches be evenly arranged in-the miter angle direction on, the intermediate layer be the parallel carbon fiber yarn bundle that stretches be evenly arranged in+the miter angle direction on, 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 ± miter angle 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.
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, 4. carbon fiber yarn bundle.
The specific embodiment
In Fig. 1, the utility model is by three layers of parallel carbon fiber yarn Shu Zucheng that stretches, three layers of parallel carbon fiber yarn Shu Youjing braided wire 2 that stretches are through weaving together, it is evenly arranged on the 0 degree angular direction for the parallel carbon fiber yarn bundle 1 that stretches at the middle and upper levels, lower floor be the parallel carbon fiber yarn bundle 4 that stretches be evenly arranged in-the miter angle direction on, the intermediate layer be the parallel carbon fiber yarn bundle 3 that stretches be evenly arranged in+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), 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 ± miter angle 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 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, and do not contain any lubricant.
