Abstract
The utility model relates to a composite warp-knitted fabric, in particular to a multi-axial warp-knitted fabric. The multi-axial warp-knitted fabric comprises a first yarn layer, a second yarn layer and binding yarns, wherein the first yarn layer is formed by plus 45-degree glass fiber net yarns; the second yarn layer is formed by minus 45-degree glass fiber net yarns; the binding yarns are used for binding the first yarn layer and the second yarn layer into a whole; the binding yarns are uniformly distributed in the warp direction on the surface of the warp-knitted fabric at intervals; that seven binding yarns are distributed per inch is used as a standard of the interval. The multi-axial warp-knitted fabric has the benefits as follows: seven binding yarns formed in the warp direction are uniformly distributed per inch at intervals, one extra yarn is added in comparison with the conventional multi-axial warp-knitted fabric, so that the hardness of the fabric is increased, and customer requirements are met further; the speed for absorbing a solution in the process of vacuum infusion in production is high; meanwhile, since the hardness of the fabric is increased, the operability of production is improved obviously, the production time is shortened, the production efficiency is improved, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of composite tricot, relates in particular to a kind of multi-axial tricot.
Background technology
High strength glass fiber fabric is widely used in the industries such as Aeronautics and Astronautics, wind-power electricity generation, automobile, pleasure boat manufacture, petroleum pipeline.Itself and resin collocation can be made high-intensity fiberglass, and the feature that this fiberglass is compared iron and steel is: intensity is higher, and weight is lighter, and corrosion resistance is better.
In wind-power electricity generation, glass fabric is the raw material of the maximum most critical of consumption during wind power generation blade is manufactured, and it is mainly used in MW class wind turbine group, as: the blades such as 1MW, 1.5MW, 2MW.
Due to blade manufacturing technique requirent, thus glass fabric have single shaft to, with multiaxis to etc. the blade desirable strength of having arranged in pairs or groups together with several series of products.And existing twin shaft to glass fiber compound material fabric as usual product E KB800 (composite code name has EKT, EKB, EKU, EKQ and UD, and wherein, E refers to E glass fibre, and k refers to tricot, and B refers to bilayer, and T refers to three layers, and Q refers to four layers, L refer to single shaft to.Along with the development in epoch, client is also more to the requirement of glass fabric, and quality requirement is also stricter.
Utility model content
The technical problems to be solved in the utility model is: in order to meet customer need, improve the performance of glass fabric, the utility model provides a kind of multi-axial tricot.
The utility model solves the technical scheme that its technical problem adopts: a kind of multi-axial tricot, tricot comprises that positive 45 degree glass fibre grenadines form the first layer, negative 45 degree glass fibre grenadines form the second layer and the first and second layers are tied to the bundled yarn of one, described bundled yarn is the uniform warp-wise in interval and distributes on tricot surface, the distance at its interval is as the criterion to be distributed with 7 bundled yarns in per inch.
In order to meet standard, the bundled yarn on the every square meter of described tricot is no more than 8g.
In order to guarantee ABRASION RESISTANCE, described bundled yarn adopts terylene thread.
The beneficial effects of the utility model are, multi-axial tricot of the present utility model, is distributed with the uniform 7 warp-wise bundled yarns in interval in per inch, increased by one than existing, can increase the hardness of fabric, further meet customer need, the absorption to solution in the vacuum perfusion process of manufacturing is very fast, simultaneously because fabric hardness increases, production operability is obviously improved, shorten the production time, enhanced productivity, cost-saving.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, tricot, 11, bundled yarn.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, embodiment of the present utility model, tricot 1 comprises that positive 45 degree glass fibre grenadines form the first layer, negative 45 degree glass fibre grenadines form the second layer and the first and second layers are tied to the bundled yarn 11 of one, described bundled yarn 11 is the uniform warp-wise in interval and distributes on tricot 1 surface, the distance at its interval is as the criterion to be distributed with 7 bundled yarns 11 in per inch.
Because the bundled yarn 11 on the every square meter of tricot 1 can not exceed 8g, therefore 7 bundled yarns 11, have been to greatest extent, and as shown in FIG., L represents that 1 inch is 25.4mm.Bundled yarn 11 adopts terylene thread.Multi-axial tricot of the present utility model, in per inch, be distributed with the uniform 7 warp-wise bundled yarns in interval, increase by one than existing, can increase hardness and the intensity of fabric, further met customer need, absorption to solution in the vacuum perfusion process of manufacturing is very fast, because fabric hardness increases, production operability is obviously improved, and has shortened the production time simultaneously, enhance productivity, cost-saving.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
