Beschreibung
Zusammenfassung:	A cellulosic composite comprises a thermoplastic polymer matrix and from 5 up to 80 weight-% of cellulose and/or lignocellulose fibers. The cellulose and/or lignocellulose fibers comprise a mixture of elongated cellulose and/or lignocellulose fibers having an average elongation equal to or lower than 0.300 and rounded cellulose and/or lignocellulose fibers having an average elongation equal to or higher than 0.325. A mass fraction of the rounded cellulose and/or lignocellulose fibers in the mixture is equal to or larger than a mass fraction of the elongated cellulose and/or lignocellulose fibers in the mixture. The cellulosic composite is an environmentally friendlier substitute for fossil-based plastics that is adapted for production of articles (30) by injection molding.
