Density measurement, tensile, and morphology properties of polylactic acid biocomposites foam reinforced with different kenaf filler loading

This paper investigates the performance of polylactic acid (PLA)/kenaf fiber (KF) composites foamed using azodicarbonamide (AC) in terms of density, mechanical, and morphology aspects. The KF loading was varied in the range of 20-40 wt. %. The mixtures were compounded using a co-rotating twin-scre...
