  • Enhancing Mechanical and Thermal Properties of Epoxy Composites Reinforced with Plasma-Treated Sisal and Pineapple Leaf Fibers
    The aim of this study was to examine the properties of epoxy composites that have sisal fiber (SF) and pineapple leaf (PF) reinforcements. Using dielectric barrier discharge (DBD) plasma for different periods ranging from 3 to 15 minutes, both fibers were treated. A combination of epoxy resin (EP), SF, or PF was prepared with or without plasma treatment. Fibers treated with plasma had a higher peak intensity of carboxyl groups in their Fourier-transform infrared spectra. A maximum tensile strength (TS) (up to 62.26 MPa) was observed in EP/SF treated for 15 minutes, but a more notable increase in elongation break (EB) (6.89 %) was observed in EP/PF treated for the same amount of time. In comparison to the sisal composites, the flexural strength (FS) of the pineapple leaf composites was found to be up to 63.2 MPa after plasma treatment. Both composites’ interfacial bonding and fiber surface roughness were enhanced by the plasma treatment. Following treatment with DBD plasma, both the wettability and thermal stability were enhanced. Composites’ mechanical, thermal, and wettability properties were improved by DBD of plasma treated surfaces, which increased interfacial bonding among the fibers and the epoxy.

  • Evaluation of sisal banana epoxy reinforced natural composite
    Natural fibres made from renewable resources, such as banana and sisal, offer enormous promise as reinforcing fibres in polymer composites and a renewable substitute for conventional fibres like glass, carbon, and wood. Banana and sisal fibres are especially prized for their advantageous mechanical qualities, low weight, accessibility, and cost. However, prior research has focused on individual fibres rather than hybrid composites. The mechanical properties of hybrid composites composed of banana and sisal fibre reinforced with an epoxy matrix are investigated in the current work in relation to loading. For gaining balanced stiffness, strength, and ductility, the proportions of fibers were optimized during the process of Compression molding in preparing composite specimens. Tensile, compressive, and impact strength were some of the mechanical properties that were evaluated according to ASTM standards. The results indicated enhanced modulus and tensile strength, highlighting the resistance of the composite to severe mechanical stress. In addition, the excellent performance under a variety of loading conditions was confirmed by compression and impact testing. These findings identify the potential of sisal-banana hybrid composites as green materials, meeting the increasing demand for sustainable, durable, and lightweight alternatives in structural applications. Unlike previous studies that primarily focus on individual natural fibers, this research highlights the synergistic effect of combining sisal and banana fibers, emphasizing the composite’s superior performance and eco-friendly attributes.

  • Characterizing the Influence of MoS2 Hybridization on the Tribological Behaviors of AZ91D-SiC Composites
    The aerospace and automotive industries are struggling to find corrosion and wear resistant lightweight materials. The AZ91D alloys’ highest strength-to-weight ratio makes them preferable than their monolithic counterparts. Hybrid composites based on AZ91D offer a viable solution to these problems. Therefore, this study set out to investigate how reinforcing AZ91D-SiC hybrid composites with molybdenum di-sulphide (MoS2) affected their tribological performance. wear resistance (WR) of synthetic composite specimen with varying percentages (wt. %) employing a pin-on-disc (POD) device was measured. Five parameters at three levels of tribological performance were evaluated using an L27 orthogonal array. The hybrid AZ91D-SiC-MoS2 composites exhibited significantly improved wear resistance in comparison to the AZ91D-SiC and AZ91D-MoS2 composites. Tribological performance of the hybrid composites was shown to be significantly affected by increases in MoS2, sliding distance (C), and load (A), as determined by analysis of variance (ANOVA) and grey-relational analysis (GRA). AZ91D 12 %, 6 % SiC MoS2 demonstrated the best multi-response tribological performance increase. Approximately 6 wt % of MoS2 reinforcement was found to be optimal. When the percentage of MoS2 particles exceeded this value, wear rise dramatically due to particle aggregation. Hybridized reinforcements boosted the composites’ hardness.
