Abstract
The invention relates to a lightweight high-strength blade and a manufacturing technology thereof. The lightweight high-strength blade comprises a blade shell and a foam die core in the blade shell, wherein the blade shell consists of continuously wrapped fiber cloth and resin coated on the fiber cloth; a fiber cloth tube and resin coated on the fiber cloth tube are arranged in the foam die core; and the foam die core is wrapped in the fiber cloth. The manufacturing technology for the lightweight high-strength blade comprises the following steps of: spreading the fiber cloth on a lower die, coating the resin on the fiber cloth, wrapping the foam die core with the fiber cloth, closing and locking an upper die when the resin in the foam die core is not cured, and demoulding after the resin is completely cured. The blade is integrally formed by adopting the upper and lower dies; and the fiber cloth in the direction of the cross section is continuously wrapped and uninterrupted, so the fatigue resistance of the blade is improved.
Description
Technical field
The present invention relates to technical field of wind power generator, relate in particular to a kind of light-high-strength blade and manufacturing process thereof that is used for wind-driven generator.
Background technique
Blade is the key position that wind power generating set effectively obtains wind energy, and the material of blade is lighter, strength and stiffness are high more, and the ability that blade is resisted load is just strong more, and blade just can be done greatly more, and its wind energy power of catching is also just strong more.Therefore, the composite material of high-strength light, good endurance becomes the first-selection of present large-scale wind generating blade.
Traditional small-sized wind power generator blade is in order to satisfy the needs of internal structure process implementing, and blade is divided into positive and negative two and adopts independently separately manufacturing of grinding tool respectively, then with its bonding forming.Such manufacturing process is discontinuous owing to make the fiber of blade in cross-wise direction, only relies on bonding strength and resists long-continued fatigue load, finally obvious visible crack occurs at separating surface, and blade will be scrapped.
Summary of the invention
To above-mentioned shortcoming, the technical issues that need to address of the present invention provide a kind of light-high-strength blade and manufacturing process thereof.
For achieving the above object; The technological scheme that the present invention adopts is: the light-high-strength blade; Comprise the foam core rod in blade shell and the blade shell; Said blade shell is for continuous fibre cloth of wrapping up and be coated in the resin on the fibre cloth, and said foam core rod inside is provided with the fiber stringing and is coated in the resin on the fiber stringing, and said foam core rod is wrapped in the fibre cloth.
A kind of manufacturing process of light-high-strength blade, said manufacturing process may further comprise the steps:
On bed die, lay fibre cloth, on fibre cloth, apply one deck resin, then the foam core rod is wrapped in the fibre cloth, when the resin in said foam core rod was uncured, the back demoulding fully of said resin solidification was treated in close upper die tooling and locking.
The present invention adopts that mould is one-body molded up and down, and the fibre cloth of cross-sectional direction is continuously a parcel, and free of discontinuities has increased the fatigue resistance of blade.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail.
Wherein: 1, upper die tooling, 2, the fiber stringing, 3, the foam core rod, 4, bed die, 5, fibre cloth.
Embodiment
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
As shown in Figure 1; Light-high-strength blade of the present invention; Comprise the foam core rod 3 in blade shell and the blade shell; Blade shell is the fibre cloth 5 of parcel continuously and the resin on the coated fiber cloth 5, and foam core rod 3 inside are provided with fiber stringing 2 and are coated in the resin on the fiber stringing 2, and foam core rod 3 is wrapped in the fibre cloth 5.
Manufacturing process like above-mentioned light-high-strength blade; Its manufacturing process may further comprise the steps: on bed die 4, lay one deck fibre cloth 5; On fibre cloth, apply one deck resin, then foam core rod 3 is wrapped in the fibre cloth 5, when the resin in foam core rod 3 is uncured; The upper die tooling 1 that closes is also locked, and treats the resin solidification back demoulding fully.Adopt that mould is one-body molded up and down, the fibre cloth 5 of cross-sectional direction is continuously a parcel, and free of discontinuities has increased the fatigue resistance of blade.
Claims (2)
1. light-high-strength blade; Comprise the foam core rod in blade shell and the blade shell; It is characterized in that; Said blade shell is for continuous fibre cloth of wrapping up and be coated in the resin on the fibre cloth, and said foam core rod inside is provided with the fiber stringing and is coated in the resin on the fiber stringing, and said foam core rod is wrapped in the fibre cloth.
2. the manufacturing process of a light-high-strength blade as claimed in claim 1 is characterized in that, said manufacturing process may further comprise the steps:
On bed die, lay fibre cloth, on fibre cloth, apply one deck resin, then the foam core rod is wrapped in the fibre cloth, when the resin in said foam core rod was uncured, the back demoulding fully of said resin solidification was treated in close upper die tooling and locking.
