Description

technical field [0001] The invention belongs to the technical field of generators, and relates to an organic composite material for generator blades and a preparation method thereof. Background technique [0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator. Converted to electrical energy by a generator. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. [0003] There are many forms of generators, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: use appropriate magnetic and conductive ma...
