    Nanocellulose, cellulose in the form of nanofibrils (CNF), has gained considerable attention in recent years as reinforcement agent for the production of composite materials due to its excellent mechanical and chemical properties, with the Young's modulus even outperforming glass fibers. However, so far the full potential of mechanical properties of CNF could not be exploited for the production of composites exhibiting properties comparable to state-of-the art engineering polymer-composites with glass or carbon fibers. This is particularly true if the goal is to produce composites completely from renewable resources [1, 2]. Thus we propose a new approach to produce nanocomposites based on nanocellulose that should enable better utilization of the outstanding mechanical properties of CNF. A new type of nanopaper from CNF has been developed and used for the production of nanocomposites. These nanopapers have been proven to exhibit significantly enhanced strength and toughness as compared to pure nanocellulose nanopapers. That is based on the introduction of various natural polysaccharides into the network of cellulose nanofibrils hindering crack propagation, thus enhancing the toughness of the material [3]. For the production of composites, these two-phase nanopapers were laminated with a standard epoxy resin. Two layers of nanopapers were laminated and these pre-forms then cured in a hot-press to result in the final composite. Of these composites, specimens for mechanical and thermo-physical measurements were produced and tested. Results indicated a significant impact of the new type of nanopapers on the mechanical properties of the composites.
