| Abstract Scope |
Due to modern extraction techniques, about 75% of an average tree can be used. This means a very large amount of waste is discarded. Thus, the objective of this work was to evaluate composites of castor oil derived polyurethane matrix reinforced with eucalyptus residues from a wood industry. To do so, composite boards reinforced with 10 up to 40% volume fraction of 3 different types of waste were made and subjected to charpy impact tests. In most cases there was a drop in performance with an increase in waste for more than 20%. With 10%, however, the strength of the composites was comparable to the pure resin, with the exception of the composite made with the intermediate size residue that presented a performance approximately 20% higher reaching 17.4 kJ / m² of impact resistance. |
