Abstract: The invention relates to a device (1) for the twist-free width change of a fiber strip (2) of continuous fibers (3) passing through the device (1) to a specified effective width (8). The device (1) comprises a transport unit (4) for transporting the fiber strip (2). The device (1) further comprises at least one width change assembly (5) configured such that the width change assembly (5) transfers an initial distance (a) of two adjacent fibers (3) of the fiber strip (2) to a target distance (b) of adjacent fibers (3) of the fiber strip (2). For a large part of the pairs of adjacent fibers (3), the ratio between the target distance (b) and the initial distance (a) matches within a tolerance range of 20%. This results in a reliable and economical device.

Abstract: 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.

Abstract: An energy-absorbing support structure has an absorbing body including a fiber-reinforced plastics material. The latter is arranged between a support structure abutment component and a support structure impact-absorbing component. The absorbing body absorbs energy by deforming from a starting state into a deformed deformation state based on an impact-induced relative displacement of the support structure components, the energy being introduced into the support structure by an impact. The absorbing body is configured as a body which has already been predeformed in the starting state by energy absorption compared to an original state. During production of the support structure, the absorbing body is firstly produced in the original state, the latter is then predeformed into the starting state and finally the absorbing body is connected to the support structure components. The result is a support structure which absorbs energy in a predictable and defined manner upon an impact-induced introduction of energy.

Abstract: In a method for the production of a molded part based on a plastic profile reinforced by incorporated fibers, with the plastic profile being heated and deformed by means of an outer or inner mold, respectively, the plastic profile is provided, preferably in the longitudinal direction, with strap-like areas which are relatively harder and less flexible at the deformation temperature of the plastic matrix than the plastic matrix itself, thus counteracting a lateral, wave-like displacement of the fibers.
