dc.description.abstract	In this study, three types of natural fiber that are bagasse, rice husk and coir were incorporated into PANI/Epoxy matrix. All natural fiber was set to the same percentage that is 5wt%. PANI/Epoxy was mixed in a container and stirred well until it become homogenously. Then, all the natural fiber was added into the PANI/Epoxy and stirred it until homogenously before put into the mould to let the composite cure for one day. The effects of thermal (Thermogravimetric Analysis, TGA, Dynamic Scanning Calorimetry, DSC), mechanical (tensile strength, modulus of elasticity, elongation at break) and morphological (Scanning Electron Microscope, SEM) were investigated. From the results, it was found that the tensile strength ofthe composite found to be decreased with addition of natural fiber. Between three types of natural fiber, bagasse fiber has the highest value of tensile strength. For elongation at break, it has been said that the elongation at break was decreased with the addition of the natural fiber. For the modulus of elasticity, there are increases in modulus of elasticity with addition of natural fiber. There are two stage weight loss behaviors that are almost at the same at 200°C and 350°C for all three types of natural fiber. Addition of natural fiber has reduced the percentage of weight loss. This indicates that addition of natural fiber into PANI/Epoxy has improved the thermal stability. The glass transition temperature (T g) was increased with the addition of natural fiber.
