The method comprises the following steps: providing a fiber bundle; pulling the fiber bundle; adding carbon nanotubes to a glue potting tank such that the carbon nanotubes and a matrix in the glue potting tank together form a potting material; impregnating the fiber bundle, which is in a pulled state, in the potting material in the glue potting tank; and pressing the fiber bundle, which is coated with the potting material, to form a carbon-nanotube-modified fiber reinforced material. In addition, the present invention further relates to an apparatus for manufacturing a carbon-nanotube-modified fiber reinforced material. According to the present invention, carbon nanotubes can be easily introduced into a material, and the introduced carbon nanotubes can be more uniformly distributed between fiber bundles or fiber filaments, such that the compression strength of the fiber bundles can be significantly improved, and the sensitivity of material strength to a manufacturing process can be reduced, thereby significantly improving the strength of the material and a blade.

Abstract

The present invention relates to a method for use in manufacturing a graphene-modified fiber reinforced material, comprising the following steps: providing a fiber bundle; stretching the fiber bundle; adding graphene to an adhesive injection tank to allow the graphene and a matrix in the adhesive injection tank to form an injection material; wetting the fiber bundle in a stretched state with the injection material in the adhesive injection tank; and extruding the fiber bundle coated with the injection material to form the graphene-modified fiber reinforced material. The present invention also relates to an apparatus for use in manufacturing the graphene-modified fiber reinforced material. The present invention ensures the concentration and even distribution of the graphene being introduced, thus significantly increasing the compression strength of the fiber bundle, thereby significantly increasing the strength of the material and a main force-bearing component of a blade, and reducing the sensitivity of material strength with respect to the manufacturing process. In addition, owing to the evenly distributed graphene, the electrical conductivity of the material is significantly increased, thus increasing a lightening protection effect of the blade.

Abstract

The invention relates to a control method and a wind turbine (1), comprising a vibration sensor (13) for measuring a vibration signal of the wind turbine (1) and a controller (15) receiving the vibration signal. The controller (15) calculates a fatigue load parameter and determines an operational limit parameter (20) for a particular operational parameter (22) based on the fatigue load parameter. The controller (15) further determines a control signal according to the operational parameter (22). If the operational parameter (22) exceeds the operational limit, then the operation mode of the wind turbine (1) is modified to bring the operational parameter (22) within safe limits again.
