Study the Micromechanical Behavior of PLA Film

Abstract:

The objective of this work is the study of the mechanical stress influence on the structural evolution. In particular, we studied the initiation and the plasticity mechanisms propagation of a semicrystalline polymer at small scales. The material is polylactic acid (PLA) film with average molar mass of 199 kg/mole and a thickness of 200 μm. The lamellate morphology of this material is very heterogeneous: in given area and packages of different orientation plates, they are spherulites α and β which have a different mechanical behaviour on a lamellate scale.
