Effect of Compounding Procedure on Mechanical Properties of PLA/PCL Blends

摘要

Side feeding technique was applied to Poly lactic acid (PLA)/Polycaprolactone (PCL) blend containing peroxide. Feeding procedures, such as blanket feed in which all the materials are fed into main hopper at once and split feeding using the side feeder, were attempted. The results indicate that tensile properties are not dependent on feeding procedure, but the impact strength was superior in the case of the split feeding samples. It is noteworthy that the impact strength of the split feeding sample was considerably affected as it was four times better. The size of the dispersed phase depends on the feeding procedure as the peroxide is more reactive when split fed.
