In this study, kenaf fiber was used as reinforcement filler for PA-6/rPE blends. The ratio of the blend to the kenaf is the most vital in this study. This is to reveal the most appropriate ratio in having the most tremendous impact on the properties of the blend. In the previous work, it has been reported that tensile and flexural strength as well as the elastic modulus of the kenaf flber-reinforced polylactic acid (PLA) composites increased linearly[9] with the incorporation of kenaf into the composites. For these reasons, this study is aimed at studying the effects that kenaf content has on two different blends of PA-6 and rPE in terms of their mechanical, thermal and morphological properties.
