In this research, rice husk and kenaf fiber were compounded with calcium carbonate (CaCO3)/high density polyethylene (HDPE) composite.Different loadings of up to 30 parts of 50 mesh sizes of rice husk particulate and kenaf fiber were compounded using twin-screw extruder with fixed 30 parts of CaCO3 fillerto produce hybrid composites of rice husk/CaCO3/HDPE and kenaf/CaCO3/HDPE.Compounded hybrid composites were prepared and tested for thermal properties. The thermal stability of the components was examined by thermogravimetricanalysis (TGA) and differential scanning calorimetric (DSC). The DSC results showed a slightly changes in melting temperature (Tm), crystallization temperature (Tc) and the degree of crystallinity (Xc) with addition of natural fiber. TGA indicates thermal stability of hybrid composite filled with kenaf or rice husk is better than unfilledCaCO3/HDPE composite.

This paper studied the thermal behaviour of pineapple leaf fiber (PALF) reinforced with polypropylene (PP) and polylactic acid (PLA) composite, used for natural fiber honeycomb core. Thermogravimetric analysis (TGA) and differential scanning calorimetric (DSC) analysis were used to measure the thermal characteristic of PALF-PP/PLA composites. In particular, the TGA analysis was utilized to measure the degradation and decomposition of materials in different composition (NF-PP/PLA (0%, 15%, 30% and 50%). The measurements were carried out in the temperature of 0oC- 900oC, at a heating rate of 10oCmin-1 and under an inert atmosphere (nitrogen gas). The temperature of DSC analysis was programmed to between 25oC- 500oC. The result shows the thermal stability of PALF-PP/PLA decreased as the PALF filler-loading increased. While from the DSC analysis this study clearly shows in the graph plot, the sample have glass transition temperature, crystallization and melting temperature. So that means the sample in this study is crystalline and amorphous domains.
