Abstract :
This work investigates the thermal, mechanical and chemical characteristics of sorghum stalks rind. Sorghum stalks have been divided into three equal regions: bottom, middle, and top. The thermal degradation behaviour has been studied using static and dynamic thermogravimetric analysis. The results of this study show that it is not recommended to subject the fibres to elevated temperatures ( 200 °C) for time periods exceeding 10 min. The highest tensile strength of 280 MPa was found at the middle region of the sorghum stalk. However, based on practical and economic aspects, the use of the complete stalk is recommended, since variations are minor. Microscopic investigation has been done for the sorghum stalk using optical microscope to relate mechanical properties to structural appearance.
