Abstract

Kenaf fiber (KF), polylactic acid (PLA) and azodicarbonamide (ADC) foaming agent were mixed evenly at two different extrusion temperatures via extrusion and followed by hot–cold pressing. The effects of two extrusion temperature profiles (P1:175, 180, 185, 170 °C and P2: 165, 170, 175, 160 °C) and the loadings of ADC (1–5 phr) on the morphological structure, and physical, tensile and thermal properties of foamed PLA/KF bio-composites were investigated. Results revealed that the tensile and water resistance properties of the foamed PLA bio-composites decreased with the increasing of ADC loadings and the number of foamed cells in the PLA/KF bio-composite foams. The P2 extrusion temperature profile appeared as more suitable blending temperature with the production of uniform porous structured bio-composite foams which having lower density and higher mechanical strength.
