摘要：

Ramie fiber reinforced poly(lactic acid) (PLA) composites were prepared by a two-roll mill Ramie was treated by alkali and silane (3-aminopropyltriethoxy silane and gamma-glycidoxypropyltrimethoxy silane) Effect of surface treatment on the properties of the composites was studied The tensile, flexural and impact strength of the composites have a significant improvement Dynamic mechanical analysis (DMA) results show that the storage moduli of the composites with treated ramie increase with respect to the plain PLA and the composites with untreated fiber whereas tangent delta decreases The Vicat softening temperature of the composites with treated fiber is greatly higher than that of the composites with untreated fiber The results of thermogravimetric analysis (TGA) show that fiber treatment can improve the degradation temperature of the composites. Moreover, the morphology of fracture surface evaluated by scanning electron microscopy (SEM) indicates that surface treatment can get better adhesion between the fiber and the matrix (C) 2010 Elsevier Ltd All rights reserved
