Abstract

The invention discloses a large-scale composite material wind-power blade which comprises a suction face shell (1), a pressure face shell (2) and a cutting webplate (3) fixedly connected between the two shells, wherein the suction face shell (1) and the pressure face shell (2) are both sandwich type structural parts of an envelope (4) for covering a core material; the core material comprises a main blade bearing beam (5), a flange reinforcement part (6) of the blade and a filling material (7) arranged between the main blade bearing beam (5) and the reinforcement part (6); and the main blade bearing beam (5) and the reinforcement part (6) both use mixtures of carbon fibers/glass fibers as an reinforcement material. The large-scale composite material wind-power blade has the advantages of light weight, extended critical length, excellent mechanical property, and the like.

Description

technical field [0001] The invention relates to a wind power blade and a preparation method thereof, in particular to a wind power blade made of composite materials and a preparation method thereof. Background technique [0002] With the improvement of wind turbine blade design technology, large-scale and lightweight has become an important trend in the development of composite wind turbine blades. At present, large-scale composite wind turbine blades mainly use glass fiber as a reinforcing material. However, the development of large-scale blades requires higher and higher strength and stiffness of blades, and the length and self-weight of blades are also increasing, so that glass fibers cannot bear it. According to the analysis of the glass fiber reinforced composite (GFRP, Glass Fiber Reinforced Polymer) blade, the critical length of the blade that its strength and stiffness can withstand is currently about 60m. Based on the requirements of the large-scale development of ...
