Abstract
The invention relates to warp-knitted cloth with three axial carbon fiber yarn layers, belonging to the field of carbon fiber composite materials. The warp-knitted cloth consists of three layers of parallel and straightened carbon fiber rovings which are warp-knitted together by warp knitting yarns, wherein the upper layer of parallel and straightened carbon fiber rovings is evenly arranged in the direction of an 0-degree angle, the lower layer of parallel and straightened carbon fiber rovings is evenly arranged in the direction of a -45-degree angle, the middle layer of parallel and straightened carbon fiber rovings is evenly arranged in the direction of a +45-degree angle, the model of carbon fiber rovings is 3K-50K, the mass per unit area of the parallel and straightened carbon fiber rovings evenly arranged in the direction of an 0-degree angle is larger than or equal to 150g/m<2> and less than or equal to 1000g/m<2>, the mass per unit area of the parallel and straightened carbon fiber rovings evenly arranged in the directions of +/-45-degree angles is larger than or equal to 75g/m<2> and less than or equal to 400g/m<2>, the laying density of the warp knitting yarns is 5 pieces per inch, and the mass per unit area of the laid warp knitting yarns is larger than or equal to 5g/m<2> and less than or equal to 12g/m<2>.
Description
Technical field
The present invention relates to carbon fiber knitted composite material field, at length say 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 processed 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 deficiency of prior art; The present invention provides a kind of three axial carbon fibres warp knitting cloths, gives full play to the mechanical property of carbon fiber, and this kind three axial carbon fibres warp knitting cloths can effectively be preset the meter reinforced fiber; Utilize the premium properties of its each part; Improve tensile property, improved cutting performance, strengthened tear resistance and interlayer performance.
The technical solution adopted for the present invention to solve the technical problems 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 invention has the beneficial effects as follows; 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 has 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 accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a structural representation of the present invention.
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 present invention 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 3K～50K (being 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.
