Abstract
AbstractIn this paper, we investigated the thermoformability of Epoxidized Natural Rubber (ENR)-filled Poly(Lactic Acid) (PLA) films using elevated temperature tensile and ball burst tests. Three different d-Lactide contents of PLA were used to be able to analyze the effect of crystallization and crystallinity. We observed that the ENR acted as a nucleating agent in PLA when the blend was cooled from melt or cold crystallized, but it retarded the drawing-induced crystallization of PLA at elevated temperature tensile testing since ENR droplets acted as obstacles. The effect of NR on PLA crystallization was also found to be dependent on d-Lactide content. In the ball burst test, different behaviors were observed for PLA with the lowest d-Lactide content, which was caused by the complex stress state that even more induced crystallization of PLA and then a single-axis tensile test.
