Abstract (en)

[origin: WO2018115738A1] Process for manufacturing a preimpregnated fibrous material having continuous fibers and thermoplastic polymer matrix, said preimpregnated fibrous material being produced as a unidirectional tape or a plurality of parallel unidirectional tapes. The process comprises a step of impregnating said fibrous material that is in the form of a roving or of several parallel rovings with said thermoplastic polymer in powder form. The D90/D10 volume ratio of the thermoplastic polymer particles is from 1.5 to 50 and the ratio of the volume mean diameter (D50) of the thermoplastic polymer particles to the mean diameter of the individual fibers of said fibrous material is from 3 to 40.
