Composites based on thermoplastic matrix and glass or carbon fibre fabrics, like the so called organic sheets, show high potential for structural parts, e. g. in automotive applications. In this study renewable organic sheets based on bio-polyamides with a melting point above 200 °C and polypropylene for reference purposes were prepared. High energy absorption for these composites were expected regarding the high elongation at break (&gt; 10 %) of the man-made cellulose fibres. In comparison to the cellulose reinforced composites, glass fibre composites were prepared. The complete or partly bio-based composites, with a thickness of approx. 2 mm, were manufactured by a high precision hot-press using the film-stacking-process considering less fibre degradation at high processing temperatures. Besides dart drop tests (penetration mode and impact mode) and optical microscopy were done to characterize the composites. The bio-based composites show lower density, higher energy absorption rates and lower damping values as a consequence of the cellulose fibres properties and the fibre-matrix-adhesion.
