Method For Preparing Composite Sheet Having Excellent Ecomomical Efficiency And Physical Property, Apparatus Thereof And Composite Sheet Prepared Therefrom

摘要

The present invention relates to a method for manufacturing a composite sheet having excellent economic properties and mechanical properties, a manufacturing apparatus, and a composite sheet manufactured therefrom, and more particularly, a) applying a first polymer powder on a release film; b) laminating the reinforcing material on the applied first polymer powder; c) applying a second polymer powder onto the laminated reinforcing material; d) heating and melting the applied first and second polymer powders; And e) pressing the molten polymer powder and the reinforcing material. The present invention relates to a method for manufacturing a composite sheet, an apparatus, and a composite sheet manufactured therefrom. ; According to the present invention, it is economical without using an existing high-cost polymer film or an extruder, and it is effective to provide a composite sheet having excellent mechanical properties such as strength and stiffness by improving the impregnation with the use of polymer powder, and a method of manufacturing the same. have. ; Composite sheet, release film, polymer, powder, coating, lamination, impregnation, strength
