People are increasingly researching and utilizing clean and renewable energy. increasingly urgent and widespread. As a clean and renewable resource, wind energy has become an important subject of research by scientists from all over the world.

The icing of wind power blades directly affects the normal operation of wind power equipment and the safety of personnel. Since wind power blades need to have sufficient structural strength and ensure light weight and fluid shape requirements, currently they are mainly made of glass fiber and carbon fiber composite materials. However, most wind turbine blades in service do not have anti-icing capabilities. Under extreme conditions, icing on the surface of the blades will directly affect the efficiency of wind power generation, and seriously cause shutdowns.

At present, there is a method of deicing the wind power blades by using the deformation of the shape memory epoxy resin material in the icing-prone area of the wind power blades. It is necessary to heat the shape memory epoxy resin material to deform it, but the invention People find that adopting this method to rely on the deformation of the shape wing epoxy resin material to deicing, the utilization rate of heat is low, the heat loss is high, and the deicing effect is not good.
