Abstract
Very good impregnation quality is achieved by a process for production of a fiber-composite material, with introducing a fiber layer by a spreader device and thus spreading to a width greater than that of the final product, at least by a factor of 1.2, where the extent of spreading of the fiber layer is such that its average thickness is 1 to 50 times the filament diameter; applying a melt by at least one applicator nozzle to the spread material; by virtue of cross-section-narrowing, the mould brings the width of the wetted fiber layer at least to the cross section with which the product leaves the take-off die; a radius then deflects the wetted fibers by an angle of 5 to 60°; a relaxation zone renders the fiber distribution more uniform to give a uniform height; achieving the first shaping by a take-off die at the end of the mould.
