This study investigates the effects of LS immersion followed by microwave treatment on tensile strength, characteristics Sansevieria trifasciata Laurentii (STL) fibers. Response methodology (RSM) with central composite design (CCD) was used optimize parameters, including time, heating temperature, duration. Mechanical, morphological, structural, properties were analyzed using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential calorimetry (DSC). Optimal conditions: 120 min at 40 °C for 30 min. They resulted a strength 370.23 MPa, 37.21% improvement compared untreated Treated exhibited enhanced stability, increased crystallinity, improved morphology. These findings demonstrate that treatments effectively STL fibers' positioning them as promising reinforcement materials sustainable applications.

Plastics are widely used in manufacturing various products due to their durability, strength, and low cost; however, they originate from nonrenewable sources. The growing interest developing environmentally friendly materials has driven research toward the incorporation of natural fibers recycled plastics. In Ecuador, Guadua Angustifolia Kunth (GaK) bamboo is usually as furniture construction materials. Therefore, this work aims reevaluate traditional use GaK fibers, exploring potentiality using chemically treated reinforcement material for thermoplastic composites. This study presents development composite based on high-density polyethylene (HDPE), HDPE (rHDPE), an experimental design that includes performing tension, flexural, impact tests obtain optimal formulation. composites were characterized optical microscopy, SEM, FTIR, DSC, TGA, EDX, followed by a life-cycle assessment (LCA). SEM images revealed morphological changes while TGA indicated significant mass loss degradation above 200 °C all DSC showed melting temperature approximately 133 samples. These results there will not be fiber during processing. highest maximum tensile strength achieved among optimization samples was 18.69 MPa. All increase Young's modulus, with enhancement up 204% compared pure HDPE, albeit marked reduction elongation percentage. flexural increased 17.84%, but decreased 83% fiber-matrix compatibility ductility composite, which allows it absorb less energy before fracture. formulation had 10% cellulose, 50% 40% rHDPE, exhibited 17.62 MPa, obtained mixture regression. LCA demonstrated rHDPE-based significantly lower environmental virgin HDPE. Using rHDPE critical reducing footprint composites, incorporating further decreases GWP emissions enhancing certain properties.

Abstract Sustainable, eco‐friendly composites have always been of great interest due to increasing environmental awareness. In this regard, there is a continuous demand for alternative sustainable materials with enhanced performance. This study focuses on the development hybrid using flax fibers, vetiver root and Luffa cylindrica fillers. Composites were fabricated varied fiber loading ratios evaluated tensile, flexural, impact, interlaminar shear strengths, sound absorption capabilities. Pure (FV) exhibited highest tensile strength (40.2 MPa), whereas containing two layers 51 g (FVL3) achieved best acoustic absorption, attenuating up 65% incident sound. Morphological analysis via SEM revealed that optimized fiber–matrix bonding well‐distributed porous network in FVL3 contributed its superior absorption. Although vetiver‐rich showed improved impact behavior, excessive content led diminished properties lower cellulose levels reduced adhesion. The results confirm balancing inclusions can tailor mechanical Consequently, recommended noise mitigation applications, such as wall panels, where moderate high are essential. Meanwhile, pure flax‐based laminates be prioritized load‐bearing scenarios requiring higher strength. Therefore, findings underscore potential flax–vetiver–luffa (FVL) hybrids alternatives structural noise‐control offering route environmentally responsible composite design without sacrificing Highlights Eco‐friendly developed flax, vetiver, luffa.
