Composites are materials which synergically combine properties of each phase – matrix and filler. Polymer materials can be used as matrix while inorganic and organic particles can be used as fillers. Composite systems based on renewable resources can be designed as an interesting material for engineering. This paper describes on the tribological and other mechanical properties of biocomposites based on polymer resins and microparticles - seed cakes, which were obtained from seeds of the plant Jatropha Curcas L. during pressing. The particle size obtained was 573 µm.The results confirmed that the epoxy and polyurethane resins were capable of forming which corresponds to the interaction with the organic particles prepared from the seeds of Jatropha Curcas L. The presence of particles however, changed the mechanical properties of the resins. In the case of epoxy resins and polyurethane (Sika Force 7723), the hardness according to Shore D identically decreased with a maximum of 1.9. Abrasion resistance decreased due to the presence of particles of 0.0393 cm3 for Glue Epox Rapid, 0.0449 cm3 for Epoxy 1200/324 and 0.0567 cm3 for Sika Force 7723.
