“…Thermoplastic polymers reinforced with high-modulus fibers are multiphase systems that attract more attention from researchers compared to thermosetting-based composites [ 1 , 2 , 3 , 4 ]. Among their numerous advantages are resistance to damage and cracking, ease of consolidation as well as fast and economical manufacturability.…”

Low-temperature plasma treatment with atmospheric discharge with runaway electrons (DRE) was shown to be an efficient way to activate carbon fiber’s (CF) surface and subsequently increase its interlayer shear strength (ILSS) values. It was demonstrated that an acceptable ILSS level was achieved after a DRE plasma treatment duration of 15 min. The treatment of CFs resulted in their surface roughness being increased and their functional groups grafting. The XPS data showed a change in the chemical composition and the formation of reactive oxygen-containing groups. SEM examinations of the PPS/CF laminates clearly demonstrated a difference in adhesive interaction at the PPS/CF interface. After the DRE plasma treatment, CFs were better wetted with the polymer, and the samples cohesively fractured predominantly through the matrix, but not along the PPS/CF interface, as was observed for the sample reinforced with the untreated CFs. The computer simulation results showed that raising the adhesive strength enhanced the ILSS values, but reduced resistance to transverse cracking under the loading pin. In general, higher flexural strength of the PPS/CF laminates was achieved with a greater interlayer adhesion level, which was consistent with the obtained experimental data.

“…Te study [13] recommended the green fller material for synthesizing the glass fbre epoxy composite through the compression moulding technique in which the 0.6 wt.% reinforcement outperformed. Te study of [14] investigated the efects of oxygen plasma treatment on polyethylene matrix and found that higher fexural strength of 25.87 MPa was observed by the novel treatment but tensile strength was slightly reduced from 18.2 MPa to 17.7 MPa. Te study [15] used benzoyl chloride treatment for the natural fbres of ramie and kenaf fbres; they optimized the weight percentage of fbres with Taguchi-based grey relational analysis and further optimized by TOPSIS technique [16].…”

This research aims to increase the utility of globally and abundantly available waste natural fibres of Gallus-Gallus fibres coir waste from mattress and car seat manufacturing factories. The composite samples were prepared with a rally round of polyester resin of grade GP500 bio-epoxy by synthesizing specially treated Gallus-Gallus fibres selectively used for reinforcement and characterizing them through static and dynamic mechanical analyses to identify their wide range of applicability. The Gallus-Gallus fibres are preprocessed with sodium oxidative and a half per cent of potassium manganate (VII) chemical solution. The selective use includes 5 mm, 10 mm, 15 mm, and 20 mm length of the Gallus-Gallus fibre, and the quantity of reinforcement was 10%, 20%, and 30%. Five alternate layers of matrix and fibres, with vertical and horizontal orientation, are considered; 12 different samples of Gallus-Gallus fibres reinforced polyester polymer composites and a neat polyester composites were synthesized and characterized for moisture absorbability, tensile strength, tensile modulus, flexural strength, flexural modulus, wear resistance, and outperformed composites were included in microscopic examination and dynamic Mmchanical analysis. The interesting results are the preferred resin, supported for good surface finish, interface bonding, and totally in the enhancement of Composite properties. The composites are strong in tension (760.89 MPa) and sufficiently flexible (flexural modulus 5441.32 MPa), absorbed less moisture (5.8 g), high wear-resistant (least weight loss upon abrasion with a value of 0.1989 g), secured good results in dynamic analysis, and ensured homogeneous distribution of fibres in the matrix through a scanning electron microscopy image. The composites CPPC10, CPPC11, and CPPC12 performed well but composite CPPC12 outperformed.

“…Among them, fiber composites are the most widely used and developed materials. The most recently used fiber-reinforcing agent is carbon fiber (CF), which is mixed with various matrix materials [1][2][3][4][5][6][7][8]. However, these carbon fibers are expensive and have disadvantages.…”

This study comparatively analyzed the behavior of elastic properties by aspect ratio of the ultra-high molecular weight polyethylene (UHMWPE) fibers that are added when creating a composite material of polypropylene and UHMWPE. The volume fraction (VF) of UHMWPE fibers added to polypropylene was fixed at 5%. The elastic properties were lumped for analysis according to the aspect ratio of the UHMWPE fibers oriented on the polypropylene matrix; they were analyzed using the Halpin–Tsai model, which involves a theoretical approach and finite element analysis based on the homogenization method. Finite element analysis was performed for fiber aspect ratios of 0.2 to 30 UHMWPE via the homogenization technique using the ANSYS Material Designer. For theoretical comparison, UHMWPE fiber aspect ratios of 0.2 to 100 were comparatively analyzed using the Halpin–Tsai model. When the aspect ratio of UHMWPE fiber was 0.2, it was calculated as 1518 MPa, and when the aspect ratio was 30, it was 2365 MPa, and it increased by 55.8%. As the aspect ratio increased, E22 and G12 converged to a constant value (1550 MPa). In the future, when the volume fraction of UHMWPE changes from 0 to 50%, a study must be conducted to analyze the predicted behavior of the elastic properties when the aspect ratio of the UHMWPE fiber changes.
