Problems solved by technology

At present, wind power generation is generally carried out through large-scale wind power blades, and the strength performance of wind power blades is particularly critical. The current wind power blades are generally formed by pouring epoxy resin into each part and then bonding them. Fibers improve the strength of wind turbine blades. The most commonly used reinforcing fibers are glass fibers and carbon fibers. However, the strength of wind turbine blades made of such materials is not very reliable and has no toughness.

Abstract

The invention discloses a wind power blade and a preparation method thereof. The wind power blade comprises an upper-side shell, a lower-side shell and edge connecting portions. The two ends of the upper-side shell and the two ends of the lower-side shell are fixedly connected through the two edge connecting portions. The preparation method comprises the steps of shell manufacturing, reinforcementrib manufacturing and edge connecting portion manufacturing. The strength of the wind power blade is comprehensively improved.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind power blade and a preparation method thereof. Background technique [0002] Wind power generation refers to converting the kinetic energy of the wind into electrical energy. Wind is a pollution-free energy source. The use of wind power generation is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries pay more attention to wind power generation. At present, wind power generation is generally carried out through large-scale wind power blades, and the strength performance of wind power blades is particularly critical. The current wind power blades are generally formed by pouring epoxy resin into each part and then bonding them. Fibers improve the strength of wind turbine blades. The most commonly used reinforcing fibers are glass fibers and carbon fibers. However, the strength of wind turbine blades made of such m...
