Abstract
The invention belongs to the technical field of wind power equipment and relates to a fan blade material. The fan blade material is prepared from unidirectional carbon fiber cloth and the following components in parts by weight: 30 to 31 parts of glass fiber cloth, 16 to 17 parts of epoxy vinyl ester resin and 0.2 to 0.4 part of a normal temperature curing agent, wherein the glass fiber cloth and the epoxy vinyl ester resin are used as base materials, the unidirectional carbon fiber cloth is used as a reinforcing material, and the area of the unidirectional carbon fiber cloth is 10 m<2>. The density of carbon fibers is about 35 percent smaller than that of glass fibers, the strength of the carbon fibers is about 40 percent, and particularly the modulus of the carbon fibers is improved by 3 to 5 times compared with that of the glass fibers; the rigidity of the prepared blade is more than 2 times that of a blade made of a glass fiber composite material; and besides, after the carbon fibers are used, the electric conductivity of the carbon fibers is used, so that the blade can be effectively prevented from being damaged by lightning strokes.
Description
Technical field
Patent of the present invention relates to a kind of fan blade material, belongs to the wind power installation technical field.
Background technology
Under the day by day shortage of current Nonrenewable energy resources, weather sharply changes, environment goes from bad to worse global context, wind energy is subject to various countries as renewable, the environmental protection energy and shows great attention to, also will be the main direction of the current utilization of new energy resources of China, also be the advanced productivity of following electric power.Account for 1/4 pricing by the blade cost in exchange, the domestic market scale of following 15 years Chinese fan blades will be above 50,000,000,000 yuan.Eleventh Five-Year Plan clearly proposes, and the localization rate of parts and components of the wind power equipments such as fan blade of newly-built wind energy turbine set must reach more than 70%, and therefore, only wind power generation has sizable development space in China the more than ten years, has formed the wind electric heating of Present Domestic.
Blower fan in the course of the work, fan blade will bear the external influences such as powerful wind loading, air scour, sandstone particle impacting, uviolizing.The present general glass fiber compound material blade that adopts the Resins, epoxy system that glass fibre strengthens for performances such as the load that improves composite material blade, corrosion-resistant and resistance to erosion, is necessary the resin matrix system is carried out well-designed and improves.
Summary of the invention
The object of the invention is to: provide a kind of lightweight, structural strength is high, manufacturing cost is low, safe and reliable to operation, installation and maintenance convenient, cost is low during whole Wind turbine per kilowatt, the fan blade material that economic return is high.
For reaching above-mentioned purpose, the invention provides a kind of wind power generator blade material, take cloth and Resins, epoxy as base material, as strongthener, described Resins, epoxy is epoxy vinyl ester resin with unidirectional lamination, each component is counted by weight:
Glasscloth 30-31
Epoxy vinyl ester resin 16-17
Ambient cure agent 0.2-0.4
Unidirectional lamination 10m
2
The composite material blade that adopts the present invention to make is lightweight, intensity is high, designability is strong, manufacturing and transportation cost are low.Because adopting the Resins, epoxy of excellent performance, improve the adhesive property of carbon fiber, resin boundary surface, improve the supporting capacity of blade, enlarge the range of application of carbon fiber in large-scale blade.The result shows that composite material blade can reach the long-term performance of using in abominable Working environment.
On the such scheme basis, described ambient cure agent is M50 peroxidation the first and second bronze medals.
The present invention compared with prior art has the following advantages and effect:
1, the density ratio glass fibre of the carbon fiber that uses of the present invention is little by approximately 35%, and intensity is about 40%, especially the modulus height 3-5 times, the blade that makes is more than 2 times of glass fiber compound material blade stiffness.
2, after the present invention uses carbon fiber, utilize the conductivity of carbon fiber, the damage to blade of can effectively avoiding being struck by lightning.
Embodiment
Take cloth and Resins, epoxy as base material, as strongthener, each component is counted by weight with unidirectional lamination:
General fibre cloth 30.5kg
Epoxy vinyl ester resin 16.5kg
M50 peroxidation the first and second bronze medal 0.3kg
Unidirectional lamination 10m
2
Take above-mentioned Material cladding moulding process as: at first strongthener is spread and covers on the mould, the profile of strongthener and laying are several carries out laying according to the blade design regulation, then inject epoxy vinyl ester resin, in the optimum viscosity and mobile singularity thereof that guarantee resin, reduce as far as possible the porosity of matrix material, guarantee that fortifying fibre keeps straight in the laying forming process, obtain the fan blade of excellent mechanical performances.
Claims (2)
1. wind power generator blade material, take cloth and Resins, epoxy as base material, it is characterized in that: as strongthener, described Resins, epoxy is epoxy vinyl ester resin with unidirectional lamination, and each component is counted by weight:
General fibre cloth 30-31
Epoxy vinyl ester resin 16-17
Ambient cure agent 0.2-0.4
Unidirectional lamination 10m
2
2. wind power generator blade material according to claim 1 is characterized in that described ambient cure agent is M50 peroxidation the first and second bronze medals.
