Preparation and characterization of oil palm fiber reinforced poly(e-caprolactone)/poly(lactic acid) composites

Palm press fibers of Tenera and Dura palm oil species of Malaysia and Nigeria respectively were used to prepare poly(e-caprolactone)/poly(lactic acid) blend composites. All the blends and composites were produced using the twin screw extruder and the test specimens were fabricated using the injectio...
