摘要： By use of a process for the production of a fibre-composite material, comprising the following steps: a) one or more fibre bundle(s) is/are drawn by way of one or more spreader device(s) into an impregnation chamber in such a way as to give at least two mutually superposed, spatially separate and spread fibre webs; b) melt is introduced by way of horizontally oriented distributor bars, in each case arranged between two fibre webs; c) the individual fibre webs are caused to converge in such a way that they are mutually superposed and contact one another; d) after the fibre webs have converged they are drawn, at the end of the operating unit, through a take-off die where the first shaping takes place, and also by use of a corresponding device, very good impregnation quality is achieved through a specific wetting method implemented after a high degree of expanding, and also through subsequent relative longitudinal and transverse movements of the individual fibres.

摘要： 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.
