HGB/PLA复合材料的制备及性能研究
Investigation on the Fabrication and Properties of HGB/PLA Composites
摘要
Abstract
The composites of poly (lactic acid) (PLA) filled with hollow glass beads (Hollow Glass Beads, HGB) were prepared by using molten blending and compression molding. The effects of HGB contents on the morphologies, mechanical properties and melt flow rate of HGB/PLA composites were investigated. The results show that well dispersed HGB in matrix and improved interfacial adhesion were observed between the PLA and HGB coated by silane coupling agent. With the increment of HGB, the specific tensile strength and elongation at break of HGB/PLA composites were increased first and then decreased; however, the specific elastic modulus exhibited the trend of continuous increase. The existence of HGB led to negative influences on the specific impact toughness, but brought on a remarkable positive impact on the melt flow rate of HGB/PLA composites.关键词
