Method for the continuous production of fibre-reinforced plastic profiles, a nonwoven material being impregnated with polymer, then deformed under pressure and/or the effect of heat to a predetermined cross section, possibly smoothed and calibrated and subsequently cured, the nonwoven material, which is supplied in a number of layers lying one on top of the other or wound in an overlapping manner being needle-punched before the impregnating operation, with the result that a continuous structure is produced. The device for carrying out the method comprises, seen in the direction of production, a supplying device for nonwoven material 11, a needle device 14 for producing a needle-punched nonwoven tube 3, an impregnating device 4, a mandrel 1, a following deforming and also calibrating and drawing-off device 16 and, following the latter, a curing device, with the deforming device, which can be driven synchronously with the mandrel, accommodating a hollow mould and, if appropriate, the calibrating and drawing-off device. <IMAGE> |
