Zusammenfassung:Composite material containing - 15 to 60 wt.-% fibers from natural sources, - 80 to 35 wt.-% polyamides, - 0,1 to 30 wt.-% additives, wherein the polyamides have a softening point below 220 °C, a heat deflection temperature above 50 °C and the polyamides consist of a) 30 to 70 mol% dimeric fatty acids, b) 30 to 70 mol% aliphatic dicarboxylic acids, c) 70 to 98 mol% aliphatic diamines, d) up to 20 mol% cycloaliphatic diamines e) up to 20 mol% polyether diamines, characterised in that the aliphatic dicarboxylic acids are selected from linear, non branched C10 to C18 dicarboxylic acids, whereby the weighted average number of C-atoms is between 11,5 to 14,5, the sum of mol% for acids and amine each add to 100.
