TLDR
In this paper, a sisal/glass reinforced polypropylene (PP) hybrid composites with short sisal and glass fibers were prepared using twin-screw extruder, followed by injection molding in the presence and absence of maleic anhydride grafted PP (MAPP) as a coupling agent.Abstract:
Hybrid composites of polypropylene (PP) reinforced with short sisal and glass fibers were prepared using twin-screw extruder, followed by injection molding in the presence and absence of maleic anhydride grafted PP (MAPP) as a coupling agent. The mechanical properties such as tensile strength, flexural strength, and impact strength increased by an optimum value at 15% sisal and 15% glass fiber loading in the presence of 2% MAPP. The rate of water absorption in the composites decreased due to the presence of glass fiber and coupling agent. The storage modulus of sisal/glass reinforced PP hybrid composites (SGRP) showed maximum improvement after treatment with MAPP. The fiber matrix morphology of the interface region in the composites was examined using scanning electron microscopy. The differential scanning calorimetry thermogram confirms higher thermal stability in the case of hybrid composites.read more
