Abstract
This research investigates the mechanical properties of natural fiber/natural resin-reinforced laminated composite panels, aiming to evaluate their potential as sustainable alternatives to traditional synthetic composites. The study focuses on characterizing the tensile and flexural behaviours of various composite formulations, including combinations of fibers with artificial resin, cashew resin (dry and wet), neem resin, and a mix of cashew and artificial resin. Standardized testing methods, specifically ASTM D3039 for tensile testing and ASTM D7264 for flexural testing, were employed to ensure accurate and reliable results. The tensile testing revealed that natural fiber composites exhibit commendable tensile strength and modulus of elasticity, with the highest performance observed in the unidirectional fiber with artificial resin. Flexural testing demonstrated robust flexural strength, particularly in composites reinforced with dry-applied cashew resin. The study also analysed failure modes, identifying typical fracture mechanisms such as fiber pull-out and matrix cracking. Comparative analysis with existing literature affirmed the findings, highlighting the potential of natural fiber composites as viable, environmentally friendly alternatives to synthetic materials. The research contributes valuable insights into the mechanical performance of these composites, supporting their application in various industries focused on sustainable manufacturing practices. The outcomes of this study underscore the importance of optimizing fiber-resin combinations and exploring advanced manufacturing techniques to enhance the properties and consistency of natural fiber composites. By addressing key gaps in the understanding of these materials, this research paves the way for their broader adoption in industrial applications, promoting innovation and sustainability in material science and manufacturing engineering.
