This research examines the impact of chemical treatment and banana fly ash fillers on mechanical, tribological, water absorption characteristics fiber-reinforced epoxy composites. Alkaline enhanced fiber-matrix adhesion, markedly improving mechanical characteristics. The optimal performance occurred at 10% content, yielding a tensile strength 40.25 MPa, flexural 77.23 an 44.82 kJ/m2. Water studies indicated decline in moisture uptake, reducing from 40% untreated composites to 25% containing 15% ash, due bonding fewer voids. Tribological experiments demonstrated decrease Specific Wear Rate (SWR) Coefficient Friction (COF) with elevated concentration, signifying improved wear resistance. Predictive modeling Artificial Neural Networks (ANN) showed accuracy (mean error: 0.9584% for SWR, 0.50265% COF). RSM optimization identified input parameters minimizing SWR COF: sliding velocity 5.14491 m/s, distance 652.05 m, content 12.6236%, minimum COF values 15.63 × 10− 5 mm3/Nm 0.242241, respectively. SEM analysis confirmed that treated fibers minimized crack propagation while fracture toughness. results underscore promise ash-filled automotive, aerospace, structural applications necessitate moisture-resistant

Abstract This study examines how NaOH treatment and alumina filler affect the mechanical properties, water absorption, thermal degradation, sliding wear of epoxy composites reinforced with pineapple leaf fiber. greatly improved composites' tensile, flexural, impact strengths by strengthening bond between fiber matrix. Furthermore, incorporation further elevated properties. The composite 10% showed peak values 41.4 MPa in tensile strength, 63.8 flexural 37.6 kJ/m 2 strength. Because hygroscopic parts were removed from treated composites, they absorbed much less water. 15% had lowest absorption at 18% after 192 h. Thermal degradation analysis that stability, having highest char residue (15.3%) 700°C.
