[0002] Wind turbine blades are the core components of wind turbines that convert natural wind energy into electricity for wind turbines. They are also the main basis for measuring the design and technical level of wind turbines. The domestic wind turbine blade manufacturing processes mainly include vacuum infusion molding and hand lay-up molding. The main body of the blade structure is basically formed by vacuum infusion molding, and blade mold closing and blade reinforcement adopt hand lay-up molding.

[0003] The current conventional hand lay-up process in the wind turbine blade industry involves manually mixing hand lay-up resin or using a small hand lay-up resin mixing device. The hand lay-up resin is then impregnated with glass fiber cloth using a scraper or a wool roller to create a glass fiber cloth prepreg. The glass fiber cloth prepreg is then manually applied to the blade workpiece or mold surface to create the corresponding hand-laid FRP component. This conventional hand lay-up process is characterized by a wide range of shape variations, rapid operation, the absence of pre-layup materials, rapid curing, and a short molding cycle. However, the quality of the hand lay-up products produced by this process still needs to be improved.

[0004] In view of this, there is an urgent need to provide a hand lay-up resin prepreg device that can improve product quality. Utility Model Content
