Description
Technical field
The utility model relates to carbon fiber knitted composite material field, at length says it is a kind of four-axial 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 four-axial carbon fiber warp-knitting cloth, give full play to the mechanical property of carbon fiber, this kind four-axial carbon fiber warp-knitting cloth 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 four-axial carbon fiber warp-knitting cloth, be provided with carbon fiber yarn bundle, it is characterized in that: by four layers of parallel carbon fiber yarn Shu Zucheng that stretches, four 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, the second layer is that the parallel carbon fiber yarn bundle that stretches is evenly arranged on an angle of 90 degrees direction, the 3rd layer for the intermediate layer be the parallel carbon fiber yarn bundle that stretches be evenly arranged in+the miter angle direction on, lower floor 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 and 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 300g/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
