Nowadays production of natural biodegradable polymer composites is an important research topic on the stage of renewable sources implementation instead of petrochemical sources. In this work, possibilities of processing biocomposites on the base on different types of biopolymers – polylactide (PLA), thermoplastic starch (TPS), polyhydroxybutyrate (PHB), cellulose acetate (CA) - filled with natural fibers such as wood, kenaf, horse hair and nettle are presented. Large variety of natural fibers and their developed surface which increases adhesion to matrix makes them an attractive filler material. The fibers serve as reinforcement by giving strength and stiffness to the structure while the polymer matrix holds the fibers in place so that suitable structural composites can be made. Main physic-mechanical properties of natural fibers and biopolymers are presented. Modulus of elasticity and tensile strength increased with rising content of natural fibers in composite. The results show that biocomposites based on starch or PHB filled with kenaf fibers has the best mechanical properties. Modulus of elasticity achieves 10-12 GPa and tensile strength 50 MPa. This property can be interesting for packaging especially for fresh food like fruits or vegetables and for technical products with short-time life cycles. In future prospects, biocomposites based on biopolymers with a long time of decomposition can be interesting alternative as a construction material in automotive sectors.
