This invention discloses an impregnation device for prepreg resin and its method of use, relating to the field of resin impregnation technology. The device comprises, in sequence according to the direction of fiber cloth feeding, a front traction roller, an impregnation tank, an extrusion roller, a pre-curing oven, and a rear traction roller. The impregnation tank contains a resin solution and a guide roller is disposed within it. The extrusion roller is positioned above the impregnation tank and behind the guide roller, and its edge is equipped with a fixed scraper along its axial direction for scraping off excess resin from the upper surface of the fiber cloth. This invention fundamentally solves the problems of uneven resin distribution along the thickness direction of the fiber cloth, insufficient resin at the edges and bottom, and the inability to expel closed-cell microbubbles in existing processes, significantly improving the interlayer bonding strength and overall density of the prepreg.
