添加剤によるPHA/PCLブレンド材の破壊挙動の変化

抄録

Polyhydroxyalkanoate (PHA) which is biodegradable plastic shows the brittleness. Therefore, our group has conducted the research to improve mechanical properties by blending Polycaprolactone (PCL) which shows high ductility. As a result, it was shown that ductility was improved slightly when 50% of PCL was blended. This research aimed at the further mechanical properties improvement in dynamic tensile test by adding the additives to blend materials. When the additives were added, it was confirmed that the maximum stress and fracture strain increased together, and, the usefulness of the additives was showed.
