Development and Characterization of Recycled-HDPE/EVA Foam Reinforced with Babassu Coconut Epicarp Fiber Residues

摘要

Nowadays, the development of polymeric materials reinforced with residues of vegetal fibers is becoming popular for application in different segments, from the automotive to the civil construction and furniture industry. Vegetal fiber residues may be used as reinforcement of the recycled polymer materials, for instance, to produce foams to packaging or to thermal and acoustic isolation for green building application. This work is focused on the development and characterization of recycled-HDPE/EVA foam reinforced with fiber residues from babassu coconut epicarp. Firstly, composites based on recycled-HDPE/EVA blend reinforced with babassu coconut fiber were obtained by melting extrusion process. The composites were then extruded in a special single screw for foaming. The foam samples were submitted to mechanical tests, density measurement, DSC, TG, and FE-SEM analysis.
