“…Now the first layer of Kevlar bidirectional fiber is placed into the die, and epoxy resin with a hardener is rolled over the thread; a hand roller is used to move and distribute epoxy resin uniformly over the fiber. The process is repeated until the completion of all layer formation sequences (Kevlar Human hair (X-direction) +Kevlar+ Human hair (Y-direction) +Kevlar) by hand layup method [2,12,14]. Finally, a constant load (20 Kg) is applied to it for the uniform formation of epoxy resin, and then it is dried out at room temperature for 24 h. After a few days, a cured sample is cut into small sizes for testing [4,10].…”

“…In the recent trend, year by year, more researchers are attracted to the use of polymer composites in a wide application of aerospace, structural, and defense applications. Compared to metal matrix composites, polymerbased composites added benefits of higher strength and less weight ratio, high density, low cycle cost, high stiffness, non-corroded, and lower water immersion [1,2]. The research involves crafting composites with human hair fibers, epoxy resin, and specific molds, adjusting hair fiber percentages.…”

The hybrid composite material, resulting from the fusion of human hair and Kevlar 29 synthetic fiber in a 10:1 ratio, reinforced with epoxy resin using the hand layup technique, underwent meticulous mechanical and thermal testing. The investigation encompassed tensile, flexural, and impact property evaluations, elucidating a notable enhancement in mechanical strength with a diminishing synthetic fiber content. Concomitantly, the composite exhibited commendable heat resistance in heat deflection tests, making it potentially suitable for applications in elevated temperature environments. Water absorption properties were scrutinized, revealing a correlation between reduced synthetic fiber content and diminished water absorption, implying heightened durability in diverse conditions. Microstructure analysis through SEM provided intricate insights into the internal composition. In summation, the composite, featuring a higher proportion of natural fibers and a lower proportion of synthetics, demonstrated superior mechanical attributes, optimal heat resistance, and reduced water absorption, showcasing its applicability in automotive and engineering domains, particularly in the fabrication of vehicle panels and components. The aim of this research represents a significant advancement in composite materials, offering a cost-effective solution that balances mechanical strength and thermal resistance. It suggests the potential for high-performance materials by combining natural and synthetic fibers, promising versatility across various applications.

Biocomposites have attracted researchers recently due to their biodegradability and environment-friendly nature. The application of new fibers is increasing to reduce the fiber cost, and easy processing, and to meet the applicationspecific properties in composite manufacturing. Banana is one of the most investigated plants for extracting fibers. Literature showed that the banana fibers were extracted from various parts of the plant. However, the potential of banana bracts is not discovered yet for composite manufacturing. In this work, the Robusta (AAA) variety banana bracts fibers (BBF) were prepared and used to make BBF reinforced polylactic acid (PLA) matrix biocomposites. Virgin PLA and BBF/PLA composites were prepared by two roll mills followed by compression molding. The characterization was carried out through X-ray diffraction (XRD), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM), and the tensile, flexural, and impact properties were evaluated for Virgin PLA, BBF, and BBF/PLA composites. The FTIR results supported the incorporation of banana bracts in the composites by increasing the cellulosic and noncellulosic components. The SEM images supported the bonding of BBF in the PLA matrix. The BBF/PLA composite possessed the tensile strength of 40.15 ± 4.32 MPa, flexural strength (FS) of 87.13 ± 5.60 MPa, impact strength of 7.41 ± 0.56 kJ/m 2 , and a crystallinity index of 48.22%, which were significantly better than the virgin PLA. It was concluded that the BBF can be effectively used for making biocomposite with good mechanical strength.banana bracts, biocomposite, green composite, natural fiber, PLA | INTRODUCTIONNatural fiber-based biocomposites have replaced synthetic fiber-based polymeric composites as a research focus because of environmental and ecological concerns.

Nowadays, industries are focusing on developing new materials which must have good durability, bio degradable and with ease of fabrication. For military application, aramid fiber is mostly preferred due to their high impact resistance property. If natural fiber is also combined with aramid fiber then industries can produce biodegradable material. Hence, this paper reviews aramid fiber (Kevlar) composites fabricated with natural fibers. In this paper, the mechanical characteristics of Kevlar composites and various combinations of natural with Kevlar composites have been discussed in detail
