Simultaneous impact modified and chain extended glass fiber reinforced poly(lactic acid) composites: mechanical, thermal, crystallization, and dynamic mechanical performance

Herein, glass fiber (GF) reinforced binary, ternary, and quaternary poly(lactic acid) (PLA) composites were prepared. Toughening, and chain extension of PLA was achieved through the incorporation of impact modifier and chain extender and their concurrent effects on the spectroscopic, crystallization...
