Abstract
The utility model relates to 90-degree carbon fiber warp knitting fabrics, belonging to the field of carbon fiber composite material. The 90-degree carbon fiber warp knitting fabrics comprise carbon fiber yarn bundles. The 90-degree carbon fiber warp knitting fabrics are characterized in that a plurality of parallel stretched carbon fiber yarn bundles are evenly arranged along the 90-degree direction and are knitted together by a plurality of warp knitting wires; the type of the carbon fiber yarn bundles is 3K-50k; the mass per unit area of the carbon fiber yarn bundles which are parallel stretched and evenly arranged is larger than or equal to 150g/m<2> and is smaller than or equal to 1000g/m<2>; the pavement density of the warp knitting wires is five wires in each inch; and the mass per unit area of the paved warp knitting wires is larger than or equal to 5g/m<2> and is larger than or equal to 12g/m<2>. The 90-degree carbon fiber warp knitting fabrics can make the best of the good performance of each part, so that the tensile strength, the sheering property and the tear resistance are improved; and due to the function of bound yarns, the friction force among the yarns is improved, so that the application range of carbon fibers is enlarged.
Description
Technical field
The utility model relates to carbon fiber knitted composite material field, at length says it is a kind of an angle of 90 degrees 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 an angle of 90 degrees carbon fiber warp-knitting cloth, give full play to the mechanical property of carbon fiber, this kind an angle of 90 degrees 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.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of an angle of 90 degrees carbon fiber warp-knitting cloth, be provided with carbon fiber yarn bundle, it is characterized in that: the parallel carbon fiber yarn bundle that stretches is evenly arranged in an angle of 90 degrees direction, by through braided wire through weaving together, carbon fiber yarn bundle model is 3K～50K, parallel stretch and evenly distributed carbon fiber yarn bundle mass area ratio more than or equal to 150g/m
2, smaller or equal to 1000g/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, improve the friction between yarn, 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 are 2. through braided wire.
The specific embodiment
In Fig. 1, the utility model is provided with carbon fiber yarn bundle 1, the parallel carbon fiber yarn bundle 1 that stretches is evenly arranged in an angle of 90 degrees direction, by through braided wire 2 through weaving together, carbon fiber yarn bundle 1 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 carbon fiber yarn bundle 1 mass area ratio more than or equal to 150g/m
2, smaller or equal to 1000g/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.
