▎ 摘  要

NOVELTY - Manufacturing fiber product (FRP) material, involves (i) weaving the processed glass fiber, basalt fiber and carbon fiber into a mixed fiber fabric with a certain size and a three-dimensional structure by the 3D mixing method, (ii) filling the mixed fiber fabric through the liquid tank filled with fiber sizing agent and immersing in the fibers sizing agent and the fiber sizing agent in the liquid tank is used to assist in infiltration by ultrasonic waves, the electric field completes further infiltration; (iii) drying the soaked fabric, and cutting into sheets with a specific size, (iv) determining the total layer number of the paving layer, then laminating according to the way of paving a layer of nano fiber film between two adjacent layers of sheets, uniformly paving the chopped carbon fiber between each sheet and the nano fiber membrane (v) removing moisture of the prefabricated body, hot pressing and molding to obtain the FRP materials. USE - Method for manufacturing FRP material for a wind turbine blade i.e. fan blade, for capturing wind energy. ADVANTAGE - The FRP material has excellent impact resistance, anti-fatigue characteristics and anti-layering property. DETAILED DESCRIPTION - Manufacturing fiber product (FRP) material, involves (i) weaving the processed glass fiber, basalt fiber and carbon fiber into a mixed fiber fabric with a certain size and a three-dimensional structure by the 3D mixing method, (ii) filling the mixed fiber fabric through the liquid tank filled with fiber sizing agent and immersing in the fibers sizing agent and the fiber sizing agent in the liquid tank is used to assist in infiltration by ultrasonic waves, the electric field completes further infiltration; (iii) drying the soaked fabric, and cutting into sheets with a specific size, (iv) determining the total layer number of the paving layer, then laminating according to the way of paving a layer of nano fiber film between two adjacent layers of sheets, and uniformly paving the chopped carbon fiber between each sheet and the nano fiber membrane, and coating the layer of the fiber sizing agents to form a prefabricated body, (v) removing moisture of the prefabricated body, hot pressing and molding to obtain the FRP materials for wind turbine blade. An INDEPENDENT CLAIM is included for an FRP material for wind turbine blade, which is prepared by the method.
