Composite materials containing 15 to 60 wt .-% of fibers derived from natural sources, 80 to 35 wt .-% of polyamide, 0.1 to 30 wt .-% of an additive, The polyamide has a softening point of less than 220 ° C., a heat deformation temperature of more than 50 ° C., and consists of: a) 30 to 70 mol% dimer fatty acid, b) 30 to 70 mol% of aliphatic dicarboxylic acid, c) 70 to 98 mol% aliphatic diamine, d) up to 25 mol% cycloaliphatic diamine, e) up to 20 mol% polyether diamine, The aliphatic dicarboxylic acid is selected from linear, unbranched C10 to C18 dicarboxylic acid, whereby the weighted average number of C-atoms is 11.5 to 14.5, the sum of the mol% of each acid and amine is 100 Characterized. |
