摘要：

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 degrees C and P2: 165, 170, 175, 160 degrees 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.
