Enhancing performance of Prosopis juliflora fiber reinforced epoxy composites with silane treatment and Syzygium cumini filler

Journal of Materials Research and Technology, Journal Year: 2024, Volume and Issue: 31, P. 93 - 108

Published: June 10, 2024

The utilization of natural fibers and fillers in composite materials has gained significant attention for their potential to enhance mechanical, thermal, tribological properties while promoting sustainability. In this study, Prosopis juliflora fiber (PJF) reinforced epoxy composites, treated with silane incorporating Syzygium cumini filler (SCF), were investigated assess performance across various parameters. composites subjected comprehensive tribological, thermo-gravimetric, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), 3D profilometer, morphology studies elucidate the effects treatment SCF content on properties. results mechanical characterization revealed improvements tensile strength, impact microhardness silane-treated higher compared untreated samples those lower content. Specifically, ST/SCF3 exhibited highest values, a strength 118.65 ± 4.63 MPa, 27.83 1.96 kJ/m2, 91.63 2.84 HV. Tribological analysis indicated enhanced wear resistance reduced coefficient friction content, demonstrating lowest loss (62 μm) frictional force (5.2 N). Thermal improved thermal stability particularly ST/SCF1 formulations, suggesting increased temperature-induced degradation.

Sustainable hybrid composites from flax, vetiver, and Luffa cylindrica: Acoustic and structural performance

Polymer Composites, Journal Year: 2025, Volume and Issue: unknown

Published: April 8, 2025

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. Alkali treatment improves fiber‐matrix Flax achieve 40.2 MPa. absorbs 59% sound, ideal applications. biodegradable reduce effectively.

Abstract In this research carbon fibers (CFs) with plasma polyethylene (PPE) was utilized for enhancing the properties. The 10 wt% CF PPE (CF/PPE) exhibited favorable electrical conductivity (34 Ω cm), better tensile strength (22.7 MPa), flexural (26.89 MPa) compared other combinations. positive temperature coefficient (PTC) test, after initial trial, CF/PPE combination a change in path at higher temperatures (125 and 128°C) due to fluctuations, which altered properties of composites. It is evident that resistivity (R) ratio exhibits values annealing samples (90°C 5 h). process resulted PTC intensity 2.53, than nonannealing (1.94). Scanning electron microscopy (SEM) analysis without procedure revealed greater number deformations combination, decrease repeatability. majority combinations enthalpy melting between 114.3 116.4 J/g. annealed heated 128°C, an increase up 122.4 point both increased from 131 134.1°C following R–T while crystallization remained unaffected.

Published: April 12, 2024

Natural fiber/degradable epoxy composites have received much attention for their advantages of low carbon emissions, environmental pollution, and utilization renewable resources. However, the poor interfacial bonding strength inferior moisture resistance natural restrict application areas. In order to improve heat resin-based composites, this study modified surfaces ramie fibers with hydroxylated nanotubes, silane coupling agents, sodium hydroxide, respectively.
