This study explored a natural fiber from Azadirachta Indica (AI) and characterize Wood–Polymer Composites (WPCs) with varying AI wood fiber compositions. Analyses and comparisons with other bark fibers in the market were conducted for various attributes. The Chemical analysis revealed that AI wood has a higher cellulose content, enhancing the strength of the filler particles, while its low wax content suggests improved interfacial bonding with the polymer matrix, making it ideal for reinforcement in polymer composites. Thermal properties of virgin LLDPE, AI wood, and their composite material were analyzed using differential scanning calorimetry and thermogravimetric analysis. The peak of the DTG curve indicated that pure AI wood exhibited higher thermal resistance. WPCs showed a decrease in flowability as wood content increased from 0 to 42% by weight, while the decomposition temperature increased, indicating improved thermal stability. The highest crystallinity index was observed in the composite with 12% wood content. Overall, the characterization of AI wood dust and its polymer composites suggests their potential for creating environmentally friendly materials for various applications.
