Abstract

The focus of this study was to investigate the effect of processing temperature and foaming agent loading on physical and mechanical properties of the foamed polylactic acid (PLA)/kenaf fiber (KF) composites. The foamed polymer composites made from PLA, KF and azodicarbonamide (ADC) were prepared via extrusion and compression molding. The temperature profile used for extrusion was set at 170, 185, 180, 175°C (high temperature profile) and 165, 170, 175, 160°C (low temperature profile). ADC loadings were varied at 0, 1, 3 and 5 phr. The density of the foamed composites exhibited a decreasing trend with the increasing of ADC loading. The morphology was analysed by Field Emission Scanning Electron Microscope (FESEM) and the results revealed the bigger size in the PLA/KF foamed composites extruded with high temperature. Tensile strength, strain @ break and Young modulus of the foamed composites decreased accordingly with respect of foaming agent content. The mechanical strength was positively affected when the lower extrusion temperature was used for extrusion.
