Granules comprising a fiber-reinforced composition (C), comprising: i) a propylene polymer (PP), having a melt index MFR2 (230 ° C, 2.16 kg) determined according to ISO 1133 in the range of 10.0 to 250.0 g / 10 min, ii) an elastomeric ethylene copolymer (E), which is a copolymer of ethylene and a C4-C10 α-olefin, iii) an adhesion promoter (AP), and iv ) short fibers (SF), selected from the group consisting of glass fibers, metallic fibers, ceramic fibers, carbon fibers and graphite fibers, where said fiber-reinforced composition (C) meets the inequality (I): ** (See formula) ** where w (PP) is the weight fraction [in% by weight] of the propylene polymer (PP), based on the total weight of the polypropylene composition (C), and w (E) is the weight fraction [in% by weight] of the elastomeric ethylene copolymer (E), based on the total weight of the fiber-reinforced composition (C). |
