Abstract
In the present work, peanut shell powder has been used as reinforcement in a matrix of HDPE from renewable sources, without and with the addition of different compatibilizers. In this case three types of compatibilizing agent (Polyethylene-graft-maleic anhydride (PE-g-MA), Polypropylene-graft-maleic anhydride (PE-g-MA) and Polystyrene-block-poly (ethylene-ran-butylene)-block-polystyrene-graft-maleic anhydride (SEBS-g-MA)) have been evaluated to check which one provides better adhesion properties between the filler and the matrix. After selecting the compatibilizing agent that provides better adhesion properties to composite, the quantity of incorporated filled was varied (0, 5, 10, 20 and 30 wt.%). Composites were mixed by a twin-screw extruder and standard specimens were obtained by injection moulding. The results show that the use of compatibilizing agents and peanut shell powder as reinforcement in HDPE composites leads to an increase in the strength properties, decreases the ductile properties and improves its thermal stability.
