  • Prepreg debacker and method of layup
    Patent number: 11155070
    Abstract: A method of removing backing film from a sheet element is provided. The sheet element has a preimpregnated layer, and sheets of backing film are adhered to the top and bottom of the preimpregnated layer. The backing film has a different coefficient of thermal expansion than the preimpregnated layer, and a plane of the sheet element is defined by the peripheral edge. A shear strain is created between the backing films and the preimpregnated layer by cooling the sheet element. A fluid stream is directed at a portion of the peripheral edge, the fluid stream being directed in the plane of the sheet element. The fluid stream causes the backing films to separate from the top and bottom of the preimpregnated layer. A differential pressure is simultaneously applied to the backing films relative to the fluid stream to cause the backing films to be removed from the preimpregnated layer.
