 The present work aimed to identify the potential of Cajunus-Cajun pod as an organic filler in fiber-reinforced polymer composites by characterizing its physical chemical, morphology and anatomy, structural and thermal properties through chemical analysis, scanning electron microscopy, x-ray diffraction, flea-transform infrared spectroscopy and thermogravimetric analysis. The results showed that the pod fiber has a diameter of about 100m, is composed of 59.15% cellulose, 10.43% hemicellulose, 21.59% lignin, 0.49% wax, 3.05% ash, and 5.29% moisture content and has a thermal resistance of up to 274 degrees Celsius. Therefore, the pod fiber could be a better alternative for synthetic fibers and preferable reinforcement for biodegradable polymeric composites. This article was offered by Irshayam Kumar, B.
