Abstract
The invention relates to a 0-degree and 90-degree angle biaxial carbon fiber warp-knitted cloth and belongs to the field of carbon fiber composites. The cloth is characterized in that one layer of parallel straight carbon fiber yarns are uniformly arranged in the direction at an angle of 0 degree; the other layer of parallel straight carbon fiber yarns are uniformly arranged in the direction at an angle of 90 degrees; the models of the carbon fiber yarns are 3-50K; the mass per unit area of the parallel straight and uniformly arranged carbon fiber yarns in the direction at an angle of 0 degree is not less than 150g/m<2> and not more than 1000g/m<2>; the mass per unit area of the parallel straight and uniformly arranged carbon fiber yarns in the direction at an angle of 90 degrees is not less than 75g/m<2> and not more than 400g/m<2>; the laying density of the warp knitting threads is five threads per inch; and the mass per unit area of the laid warp knitting threads is not less than 5g/m<2> and not more than 12g/m<2>. The cloth has the following beneficial effects: the excellent performances of each component of the carbon fibers can be fully utilized, so that the tensile strength, the shear performance and the tear resistance are improved; and due to yarn binding, the friction between the yarns is improved and the interlayer performance of the fabric is enhanced, thus expanding the application range of the carbon fibers.
Description
Technical field
The present invention 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 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 0 degree and an angle of 90 degrees twin shaft to carbon fiber warp-knitting cloth, gives full play to the mechanical property of carbon fiber, and this kind 0 degree and an angle of 90 degrees twin shaft can effectively be preset the meter reinforced fiber 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 solution adopted for the present invention to solve the technical problems 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, and wherein one deck is that the parallel carbon fiber yarn bundle that stretches is evenly arranged on the 0 degree angular direction, and 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 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.
The specific embodiment
In Fig. 1; The present invention 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, and 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 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.
