Abstract
Social development combined with economic progress and the preservation of natural resources forms the basis of the sustainability concept. In this sense, a productive model based on this strategy was established as an alternative to forest wood in the furniture industry by extruding wood-plastic composite (WPC) bars made of recycled HDPE and babassu coconut shell fibers. Temperature calibration of the extrusion set was conducted to verify the surface quality of the bars. The best surface aspect and lowest porosity were reached for higher extrusion temperatures and low speed, and these conditions were used for producing the samples for experimental tests on the material's resistance. The analysis of the stress-strain curves showed that natural wood alone behaves similarly to brittle materials in which there is little plastic deformation before rupture, whereas the additions of HDPE improved the total elongation and impact resistance substantially. The good mechanical properties validate the use of this material and the proposed production model, which promotes social integration in the babassu extracting economy chain in one of the poorest regions in Brazil.
