Mechanical and Antistatic Properties of Hybrid Fiber-Reinforced Composites with Lignocellulosic and Recycled Carbon Fibers

In order to enhance the mechanical properties of poly(lactic acid)/polypropylene polymer alloys, hybrid fiber-reinforced composites (hybrid-FRC) were investigated, including recycled carbon fibers, which have a homogeneous morphology and ultra-high mechanical strength and bamboo-derived lignocellulo...

Description
Summary:In order to enhance the mechanical properties of poly(lactic acid)/polypropylene polymer alloys, hybrid fiber-reinforced composites (hybrid-FRC) were investigated, including recycled carbon fibers, which have a homogeneous morphology and ultra-high mechanical strength and bamboo-derived lignocellulosic fibers, which have a rigid tissue structure, high mechanical performance and a low thermal expansion coefficient. Moreover, effects of a compatibilizer, maleic anhydride-modified polypropylene (MAPP), were examined. The addition of MAPP increased the interfacial shear strength of polymer alloys on carbon fiber surfaces. The hybrid-FRCs showed excellent tensile strength, 168.7% higher than the polymer alloy. Moreover, the antistatic effect was considerably increased by the hybridization, suggesting synergistic effects of both fibers. Therefore, it was clarified that the hybrid-FRCs are useful and powerful materials.
