Abstract
Green composites are expected as alternative materials of multipurpose plastics. As the runup to green composites, it is necessary to explain various properties of matrix. This study reported the effect of water Environment on mechanical properties of matrix (PLA). As a result, PLA absorbed water in water environment and its mechanical properties decreased with increase of water absorption. On occasions When PLA was in water environment at high temperature and for a long time, its mechanical properties decreased with development of degradation. It is recognized, by observation of specimens and decreasing of its weight, that this decreasing of mechanical properties are caused by corrosion layer weaken by elution. And It is recognized by FT-IR analysis that Corrosive layer was caused by ester hydrolysis.
