摘要：

This study evaluated reinforcing effect of waste lignocellulosic material (bagasse) and nano-SiO2 powder on physical and mechanical properties of nano-biocomposites. In the specimen preparation, three levels of nano-SiO2 (0, 2, and 5 wt%) and 40 wt% of fibers were used. In order to increase the interphase adhesion, polyethylene grafted with maleic anhydride was added as a coupling agent to all composites studied. The results showed that while tensile, flexural, and hardness properties were moderately improved by adding bagasse fibers and increasing nano-SiO2 (NDS) content, Izod impact strength decreased dramatically, but fibers filled composite with 5 wt% nano-SiO2 showed similar impact strength value to pure HDPE specimen. Natural fibers and increasing levels of nano-SiO2 particles led to an upward trend for water absorption, while thickness swelling sharply increased and leveled off with adding these fillers. The results of study demonstrate positive effects of waste lignocellulosic material and nano-SiO2 particles on physical and mechanical properties of composites. © 2014, Indian Academy of Wood Science.
