Abstract
Logging waste is generated in large volumes during the mechanical processing of wood, causing considerable environmental impacts, such as soil and water contamination. In this research, wastes collected in a typical sawmill for the manufacture of slats, boards and pallets were used. The objective of this work was to characterize chemically waste of Eucalyptus spp. for reinforcements in polypropylene composites, investigating the use of polypropylene compatibilizer with maleic anhydride and to evaluate the mechanical properties in tensile and flexural tests analyzing different formulated compounds. Initially, the residues were dried and separated in sieves for granulometric classification. The quantitative chemical composition of the wastes was determined according to the precepts of the technical standards. Composites with different concentrations of polypropylene, polypropylene with maleic anhydride and residues were produced in an interpenetrating, corotative twin screw extruder and injection molded in the form of tensile and flexural test specimens. The tensile tests results indicated that the addition of filler raises the Young’s modulus and the compatibilizer provides increase in the tensile strength. The flexural tests results indicated that the addition of filler raises the flexural modulus and the compatibilizer provides increased flexural strength and maximum deflection.
