Wind turbine generator blade with microwave directional deicing function and manufacturing and deicing method thereof

The invention discloses a wind turbine generator blade with a microwave directional deicing function and a manufacturing and deicing method of the wind turbine generator blade. The front edge part and the blade tip part of the blade are made of a metal nanoparticle/carbon fiber/epoxy resin composite material with high wave absorbing performance; a plurality of high-power magnetrons are mounted at blade root positions of blades of the wind turbine generator and are configured to be uniformly distributed at a certain mechanical angle, and micro steering engines are mounted at antennas of the magnetrons and are used for controlling the direction of microwaves; and a metal foil with high microwave reflection capability covers the I-shaped beam close to the front edge of the blade in the blade cavity. When ice is formed on the blade, the high-power magnetron and the steering engine which are installed at the blade root position of the blade are started, directional microwaves are sent out, the microwaves are refle
