METHOD AND DEVICE FOR PRODUCING A COMPOSITE FIBRE MATERIAL IN THE FORM OF A FIBRE STRIP IMPREGNATED WITH A POLYMER

A device for producing a composite fiber material in the form of a fiber band impregnated with a polymer includes a transport device for supplying and for transporting a fiber band along a processing path. To preheat the raw fiber band to a processing temperature a preheating device is used. An application device is used for applying the melted polymer on the whole width onto the surface of the raw fiber band. At least one pressure shearing vibration application device is used to apply pressure to the raw fiber band perpendicular to the band plane after the application of the polymer, where the application of pressure is performed by at least one pressure stamp with the simultaneous shearing vibration of the pressure stamp by a vibration movement component (y) in the band plane and transversely to a band running direction. At least one tempering device is used to keep the raw fiber band within a processing temperature range. This results in a production method and a production device with a predefined impregnating quality at the lowest possible production cost.
