Characterization of mechanical properties of jute/PLA composites containing nano SiO2 modified by coupling agents

Although jute fiber-reinforced PLA composites show strong application prospects, their low mechanical properties limit applications to some extent. In this paper, nano-SiO2 particles as well nano SiO2 modified by coupling agents which can efficiently improve the strength and toughness of composite materials are introduced into matrix. The bending, stretching thermal designed jute/PLA nonwoven were studied. study shows that beneficial interface performance between matrix leading improvement in stability. Moreover, thermomechanical indicate addition interfacial adhesion increase glass transition temperature material. Finally, toughening mechanism was analyzed.
