Optimization of Glass Fiber /Polyester with Natural Fillers Hybrid Composites Using TOPSIS Approach

In recent years, the drive toward sustainable and cost-effective composite materials has prompted growing interest in the consolidation of natural fillers into artificial fibers. This paper investigates the mechanical, physical and wear attributes of glass fiber-reinforced polyester composites adjusted with differing quantities of natural fillers (banana chopped, rice husk, wood powder and wheat straw). Fiber content, orientation, kinds, length, and other parameters all affect a composite material’s mechanical, physical, wear, and water absorption behavior. This study aims to investigate the effects of varying natural filler loading on the mechanical, wear, water absorption, and physical characteristics of polyester-based hybrid composites reinforced with glass fiber and natural fillers. Using a straightforward hand lay-up process, composites of varied compositions are created with four distinct filler loadings, 5% to 15%, with a 5% range and glass fiber loading that is constant (20 wt%) with a constant matrix material (polyester resin). The performance of polyester-based hybrid composites reinforced with glass fiber and natural fillers has been found to be significantly impacted by filler loading. The best option among a group of options is also chosen to use TOPSIS, a multi-criteria decision-making technique. The TOPSIS results ranked the hybrid composites based on their proximity to the optimal solution, thereby providing a systematic and quantitative method for material selection.
