NOVELTY - Continuous fiber reinforced composite material is stacked, polyurethane foam comprising polyol and isocyanate and stacked composite materials are molded, obtained prepreg sheet is passed through plate-forming machine (2) and glue box (4) containing adhesive, in order, obtained sheet is passed to crawler-type pressing machine (6), pressed, extruded, and passed into molding machine (5) to obtain polyurethane foam sandwich. Reinforced composite is filled and rolled into reinforced composite plate, obtained plate is laminated to the obtained sandwich, to obtain sandwich panel.    USE - Molding of continuous fiber-reinforced polyurethane foam composite sandwich panel used for car, wind-power generation and buildings.    ADVANTAGE - The continuous fiber reinforced polyurethane foam composite sandwich panel is effectively used as a substitute of steel and plastics, and is light weight, has high strength, waterproof property, and damp-proof property.    DETAILED DESCRIPTION - Continuous fiber reinforced composite material is cleaned, polished to predetermined surface roughness, stacked on plate stack (1), polyurethane foam comprising polyol and isocyanate and stacked composite materials are molded in plastic molding machine (5), obtained continuous fiber reinforced composite prepreg sheet is passed through plate forming machine (2) into double layer oven (3) to form sheet, formed sheet is passed through glue box (4) containing adhesive at certain temperature and soft roller (4-1), sheet is then passed to crawler-type pressing machine (6), prepreg sheet attached with polyurethane foam on both sides is extruded, and passed into molding machine (5). Obtained polyurethane foam sandwich containing two subcomponents of same material is passed into foam plate composite article traction machine (7), reinforced composite is filled and rolled into reinforced composite plate, obtained reinforced composite plate is laminated to resultant sandwich, surface of obtained sandwich is cleaned, smoothened, cut by cutting machine (8) to desired length, obtained sandwich panel is detected, and stored.
