Composite material containing cellulose fibers and having high impact strength

A composite material being obtainable by blending the components (a) to (g), and optionally component (h):

• (a) from 10.0 to 35.0 wt. % of a first heterophasic propylene-ethylene copolymer (HECO1) having a melt flow rate (MFR2), determined according to ISO 1133 at 230° C. and 2.16 kg, in the range from 60 to 200 g/10 min,
• (b) from 5.0 to 25.0 wt. % of a second heterophasic propylene-ethylene copolymer (HECO2) having:
• a melt flow rate (MFR2), determined according to ISO 1133 at 230° C. and 2.16 kg, in the range from 4 to 30 g/10 min, and
• a soluble fraction (SF), determined according to CRYSTEX QC analysis, in the range from 17.0 to 40.0 wt. %, relative to the total weight of the second heterophasic propylene-ethylene copolymer (HECO2),
• (c) from 8.0 to 40.0 wt. % of a mixed-plastic polypropylene blend having a polypropylene content of at least 75 wt. %, based on the total weight of the mixed-plastic polypropylene blend;
• (d) from 8.0 to 18.0 wt. % of an ethylene-based elastomer being a copolymer of ethylene and an alpha-olefin co-monomer having from 4 to 12 carbon atoms, and the ethylene-based elastomer having a density in the range of 850 to 900 kg/m3,
• (e) from 5.0 to 30.0 wt. % of cellulose-containing fibers,
• (f) from 1.0 to 5.0 wt. % of a compatibilizer being a polar modified polypropylene or a polar modified elastomer,
• (g) from 0.1 to 5.0 wt. % of additives,
• (h) optionally from 0.1 to 15.0 wt. % of a high density polyethylene, wherein the weight amounts of components (a) to (h) are defined relative to the total weight of the composite material.
