Cellulose nanofiber can be obtained from natural or waste wood by acid hydrolysis (nitrc acid). In this research we would report a process for producing nanofibers of cellulose with crystallinity index of approximately 82 %. We chose to work with certified eucalyptus by Forest Stewardship Council (FSC) to ensure a perfect reproducibility of future experiments. A wood sample was subjected to acid hydrolysis during almost 300 minutes. The resulting mass was filtered in a vacuum system and dried during one hour in an oven at temperature about 100 °C. Before this was realized an X-Ray diffraction (XRD) analysis to be sure of the crystallinity. Cellulose nanofiber has a greater axial elastic modulus (Young’s modulus) than Kevlar and its mechanical properties are within the range of other reinforcement materials. Cellulose nanofiber can be a new material to reinforce some polymeric filament like polylactic acid (PLA) or acrylonitrile butadiene styrene (ABS).
