Natural-based lignocellulose fibrous materials can be used as a sustainable alternative to conventional fossil-based fibers such as glass fibers, in lightweight fiber-reinforced thermoplastic composites for marine, automotive, aerospace, or other advanced applications. However, one of the main challenges in using natural fiber-based thermoplastic composites is the low mechanical performance of composite structures. This can be improved significantly through the development of an optimized novel fiber architecture with enhanced fiber packing properties, following a low-cost production process. In this context, this study demonstrates a less energy-consuming and cheaper manufacturing process, for developing highly individualized short jute fiber-based dry fiber preform architecture, with an improved fiber packing property. Short jute fibers were chemically treated with alkali and PVA sizing treatments in the processing of new fiber preform architectures, and they were used in manufacturing of ultimate short jute fiber/polypropylene (PP) thermoplastic composites. The newly developed short fiber thermoplastic composites showed a significant improvement in mechanical properties (tensile, flexural, and impact) compared to any other natural fiber architecture-based (woven, knitted, nonwoven, unidirectional, etc.) composites found in the literature. Due to the use of new fiber architecture, the developed composites' fiber content was observed to increase. In addition, the compatibility of jute fibers with the polypropylene matrix was strengthened with the application of chemical treatments on highly individualized jute fibers. These reasons were responsible for the enhancement of mechanical properties of developed composites. Micromechanics of the fibers in composites were evaluated using the modified rule of the mixture and Halpin−Tsai equations for stiffness prediction of the composites in order to develop a theoretical understanding of newly developed composites' mechanics. It is thought that the improved mechanical performance of short jute fiber/PP thermoplastic composites can extend the use of these composites in many load-demanding applications, wherein normally synthetic fiber composites are used.

“…In modern society, polymer-based composites are in high demand due to their high strength-to-weight ratio, good thermal stability, wear and corrosion resistance, vibration and damping properties when used in applications [1][2][3] which include aerospace industries, automotive vehicles, medical implants, and in various engineering fields as well as the small-scale sector. [4][5][6] Most polymer based composites are fabricated using thermoplastics, thermosetting plastics as the matrix material. As thermoplastic is unsuitable with high temperature, thermosetting based plastics are used in high temperature applications.…”

Wear testing, in this research was conducted for compression molded flax and ramie fibers with epoxy resin matrix. The 40 wt% fiber combination was used for a fiber length (FL) of 0.5–1.5 cm while varying sliding distance (SD) ranged from 500 to 1500 m. Better results were obtained in 1000 m SD and 1 cm FL with a specific wear rate (SWR) of 13.12 × 10−5 mm3/Nm. Samples with 50 wt% natural fiber combinations were tried with different FL (0.5–1.5 cm) and sliding speed (SS) from 0.5 to 1.5 m/s. Sliding speed increased the contact between the sample and the counter steel disc, which caused high wear rate in the specimen. A high SWR was observed for the combination of SS 1.5 m/s, 0.5 cm FL due to high contact and with lower adhesion of fiber/matrix phase than in the others. Higher FL damages the compatibility of matrix/reinforcement phases, which makes the epoxy sample highly brittle with less wear resistance. The combination of 30 wt% natural fiber with FL (0.5–1.5 cm) and load 5–15 N showed high wear rate at a higher load of 15 N (31.57 × 10−5 mm3/Nm). SEM results with 50 wt% NF combination, 0.5 cm FL at 5 N load showed high deformation in the natural fiber structure compared to the 40 wt% NF combination, mainly due to the adhesion of fiber with epoxy resin which acted as a stress transfer area allowing transfer of more loads.

Synthetic fibers as reinforcement in composites are inevitable in today's composite industry due to its exceptional mechanical properties. The objective of this paper is to investigate the effect of stacking sequence of carbon, glass and Kevlar bidirectional (0 /90 ) woven mat synthetic fibers reinforced in epoxy matrix composite with silicon carbide (SiC) nanoparticles as filler material on mechanical and visco-elastic behavior of developed novel hybrid polymer matrix composites (HPMCs). Vacuum bag infusion method is adopted to manufacture the composite specimens by stacking carbon, glass and Kevlar fibers alternatively with six layers and six different stacking sequences and tested as per ASTM standards. Tensile, flexural, impact and hardness test is conducted to identify the composite specimen with maximum mechanical characteristics. The maximum tensile and flexural strength of 398.178 and 671.25 MPa respectively is seen for the composite with strong fibers such as carbon and glass stacked away from the neutral axis. Also, the scanning electron microscope (SEM) images of tensile and flexural failure specimen revealed the failure mechanisms of developed composite specimens. Moreover, the dynamic mechanical analysis (DMA) revealed the visco-elastic behavior of developed composites with glass transition temperature (T g ) at 115 C. This study emphasizes the influence of stacking sequence on thermo-mechanical properties of the developed HPMC specimens and explores its potential for diverse applications.
