Abstract
Dynamic Mechanical Analysis is carried out on treated and untreated kenaf, thespesia lampas and okra fiber polyester composites. Results indicate that composites with fibers treated by sodium hydroxide have higher storage modulus, decreased loss modulus and damping factor Best properties are noted for treated okra fiber composite with highest storage modulus and glass transition temperature and lowest damping factor. The Scanning Electron Microscopy results indicate a superior interfacial bonding for treated kenaf fiber composite. Improved interfacial bonding upon treatment causing hindrance to the mobility of molecular chains can be seen clearly in the micrographs. The effect of chemical modification of the fibers in enhancing the dynamic mechanical properties is well demonstrated for kenaf, thespesia lampas and okra fiber composites in this paper.
