This study addresses the challenge of simultaneously optimizing flexural and impact properties along with structural integrity by employing a novel (0°/90°/0°/90°) stacking configuration using both plasma-treated and untreated fiber preforms. Composites were fabricated through compression molding, placing rHDPE sheets strategically within a four-layer fiber stack and applying 5-ton pressure at 160°C for 15 min, followed by a 24-h curing period. Plasma treatment drastically influenced the adhesion of fiber and matrix, leading to an increased impact strength and altered behavior of water absorption. The greatest impact strength of 31.86 kJ/m<sup>2</sup>—a 45.4% improvement over its untreated counterpart—was found in the plasma-treated hybrid composite (plasma jute–banana composite [PJBC]) with a 7.6% flexural strain, signifying improved energy dissipation and ductility. However, flexural strength in hybrid composites decreased marginally (from 21.3 to 20.3 MPa) due to increased surface brittleness. Plasma treatment improved water absorption in jute composites (0.13%) via increased porosity, but hybridization minimized the effect to yield balanced moisture absorption and mechanical properties. The synergistic combination of jute stiffness and banana flexibility in hybrid form, with plasma-induced surface activation, resulted in composites with optimal structural integrity and sustainability.

This study seeks toward optimization of key process parameters in fuzed filament fabrication (FFF). Improving the mechanical integrity and adaptability of biomedical-grade PLA components is the goal. Researchers systematically designed experiments that evaluated how four critical FFF parameters, layer thickness, wall thickness, infill density, along with infill pattern, influence tensile strength and fatigue life. For fabricated PLA specimens, standardized tensile tests in addition to low-cycle fatigue tests were used through varying combinations regarding these parameters. The results demonstrated that a layer that was 0.3 mm thick greatly improved fatigue life (1099 cycles) as well as tensile strength (39.8 MPa), while thinner layers performed worse. Wall thicknesses upto 3 mm improved fatigue performance however tensile strength gains lessened with later increases. At the 0.75 infill density, the mechanical performance was optimal (fatigue life: 1070 cycles, tensile strength: 39.6 MPa) but lower densities decreased durability. The grid structure has provided for the best balance between the strength and the fatigue resistance among all the infill patterns. It had better performance than Tri-hexagon and gyroid structures. One-way analysis of variance (ANOVA), that is a statistical validation, confirmed the importance of layer thickness and infill density for the mechanical outcomes at <i>p</i> < 0.0001. These findings suggest PLA components suitable for load bearing and bioresorbable medical applications can be yielded by careful tuning of FFF parameters.
