Abstract
The utility model discloses an axial fan glass reinforced plastic blade is strengthened to carbon fiber, include a confined blade casing that forms by epitheca and inferior valve butt joint, the blade casing divide into the multilayer glass fiber layer and fibre layers, blade casing inlayer and skin are glass fiber layer, the adjacent setting of glass fiber layer and fibre layers. The utility model discloses the beneficial effect who reaches does: adopting two kinds of materials on glass fiber and the carbon fiber, adopting the adjacent setting of different material layerings, compare with glass fiber, carbon fiber density is little, intensity is high to reach the mesh that alleviates blade weight, increase strength.
Description
Technical field
The utility model relates to air-cooled vanes technical field, is specifically related to a kind of carbon fiber reinforced shaft flow fan fiberglass blade.
Background technology
Modern fan blade mainly uses glass-reinforced plastic material to produce, and fiberglass has higher specific strength compared with timber and metal, is particularly suited for manufacturing as the large scale thin layer member of fan blade etc.Reinforcing fiber the most commonly used in glass fiber reinforced plastics composite material is carbon fiber and aramid fiber.The intensity of carbon fiber is the twice of glass, and modulus is three times of glass, and high-modulus makes carbon fibre composite have more preferable fatigue behaviour.Existing Fan blade material is glass fibre, and glass fibre advantage is good insulating, heat resistance is strong, corrosion resistance good, and mechanical strength is high, but shortcoming is that property is crisp, and wearability is poor, weight is big, intensity is low, and the cost of carbon fiber is high.How to reduce the weight of blade, improve intensity, meet fan operation demand, the most cost-effective, it is one of the problem of current the sector research.
Utility model content
It is little that technical problem to be solved in the utility model is to provide a kind of weight, and intensity is big, improves a kind of carbon fiber reinforced shaft flow fan fiberglass blade of fan efficiency.
For solving above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of carbon fiber reinforced shaft flow fan fiberglass blade, including the blade shell being docked the closing formed by upper casing and lower casing, it is characterized in that: described blade shell is divided into multilayer, including glass layer and carbon fiber layer, blade shell internal layer and outer layer are glass layer, glass layer and carbon fiber layer and are disposed adjacent.
Further technical scheme is: described blade shell is divided into three layers, and outer layer is the glass layer of 1～2 layer of glass fabric, and middle level is carbon fiber layer, and internal layer is glass layer, and the thickness of middle level and internal layer ratio is for 1:5～10.
Use and have the beneficial effects that produced by technique scheme:
Using glass fibre and carbon fiber bi-material, use different materials layering to be disposed adjacent, compared with glass fibre, carbon fiber density is little, intensity is high, thus reaches to alleviate leaf weight, the purpose of raising intensity.
Accompanying drawing explanation
With detailed description of the invention, the utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model cross section.
Wherein: 1-blade shell, 2-glass layer, 3-carbon fiber layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of the utility model protection.
Elaborate a lot of detail in the following description so that fully understanding the utility model, but the utility model can also use other to be different from alternate manner described here to be implemented, those skilled in the art can do similar popularization in the case of the utility model intension, and therefore the utility model is not limited by following public specific embodiment.
As shown in Fig. 1～2, a kind of carbon fiber reinforced shaft flow fan fiberglass blade, including the blade shell 1 being docked the closing formed by upper casing and lower casing, described blade shell 1 is divided into multilayer, including glass layer 2 and carbon fiber layer 3, blade shell 1 internal layer and outer layer are glass layer 2, glass layer 2 and carbon fiber layer 3 and are disposed adjacent.
Further preferred that described blade shell 1 is divided into three layers, outer layer is the glass layer 2 of 1～2 layer of glass fabric, and middle level is carbon fiber layer 3, and internal layer is glass layer 2, and the thickness of middle level and internal layer is than for 1:5～10.
Glass fibre advantage is good insulating, heat resistance is strong, corrosion resistance good, mechanical strength is high, carbon fiber " soft outside but hard inside ", density is lighter than metallic aluminium, but intensity is higher than iron and steel, and it not only has the intrinsic intrinsic property of material with carbon element, have both again the soft machinability of textile fabric, density is low, superhigh temperature resistant under non-oxidizing atmosphere, and fatigue durability and corrosion resistance are the most fine.Both are combined and alleviate the weight of blade by the utility model, add intensity, improve fan efficiency.
