摘要

The development of hybrid natural-synthetic fiber composites offers a sustainable direction to high-performance materials for structural applications. This study presents a statistical method to estimate and optimize the mechanical characteristics of E-Glass/Jute/Banana fiber-reinforced polymer composites using the RSM method. Composite samples were fabricated using the hand lay-up technique by varying three critical parameters: Epoxy Resin (ER) content, Curing Temperature (CT), and Curing Period (CP). Mechanical tests were conducted to evaluate Ultimate Tensile Strength (UTS), Flexural Strength (FES), Impact Strength (IMS), and Shore Hardness (SHS). The interaction between CT and CP (43.09%) was identified as the most significant factor influencing UTS, followed by CT (18.53%) and ER (15.85%). Perturbation analysis revealed that CT positively influenced UTS, FES, and IMS, while CP had a favourable impact on SHS. Optimal mechanical performance was achieved at ER of 260 g, CT of 75.991 °C, and CP of 24 h, yielding a desirability of 0.713. Under these optimized conditions, the composite exhibited UTS of 218 MPa, SHS of 83.6 Hv, FES of 243.6 MPa, and IMS of 10.2 J.
