“…The several forms of reinforcement (short, long, and woven) have a considerable impact on the final properties of composites, with woven fabric reinforcements being the most feasible, exhibiting the best structural integrity with the polymer matrix. [19][20][21][22][23][24][25][26][27][28][29][30] Dynamic mechanical properties of composites play an important role in structural applications. The dynamic mechanical analysis (DMA) explains the sample's stiffness and energy loss of sample during cycling loading.…”

The current experimental investigation examines the effect of the warp/weft orientation of jute/sisal and flax/kenaf fibers on the static and dynamic mechanical characteristics of intra-woven hybrid composites. Jute (J), sisal (S), flax (F), and kenaf (K) hybrid woven mats were explicitly designed to keep fibers in the warp and weft directions. Intra-hybrid-composites with JJ, JS, SJ, SS, FF, FK, KF, and KK type hybrid woven mats with polypropylene matrix were processed using the compression molding/film stacking method. The tensile and flexural, and the dynamic mechanical behavior was investigated. Utilizing a scanning electron microscope, the fractured surface of tensile test specimens was examined. The results indicate that combining jute with sisal and flax with kenaf improved the mechanical properties of pure sisal and kenaf based composites. Hybridized composites exhibited the maximum increment in tensile strength (5.95% and 31.16%), tensile modulus (4.20% and 66.64%), flexural strength (12.59% and 5.69%), and flexural modulus (47.10% and 19.72%) for JS and FK composites, when compared with unhybridized SS and KK composites, respectively. The fiber hybridization and warp/weft sequence have a substantial effect on the dynamic mechanical performance of woven fiber laminated composites. It was identified that composites of JS and FK possess a higher storage modulus than pure SS and KK based composites, respectively. In addition, at a temperature of 50 C, the storage modulus was improved by 37.63% and 136.63%, for JS and FK hybrid composites, respectively in comparison to the unhybridized SS and KK composites, respectively.

“…Jute, which has a smaller microfibril angle (~8.0°) and a greater cellulose content, 16 is composed of the following: 61%–71% cellulose, 14% hemicellulose, 12% lignin, 0.2% pectin, 0.5% wax, and 10% water. Due to its remarkable attributes including low density, moderate moisture regain, elevated stiffness and specific strength, good electrical and thermal insulation, biodegradability, low cost, and commercial availability, jute is widely regarded as the preferred bast fiber for use as a reinforcement material 16–22 . Conversely, there is a growing trend of using hemp fibers into composite materials as reinforcing agents, often in place of glass fibers due to their better strength and stiffness 23,24 .…”

One of the primary drawbacks associated with natural fiber reinforced composites is their relatively poor mechanical properties. One potential approach to overcome this challenge is to augment the fiber loading, thereby improving the interfacial characteristics and hybridization. In this study, hybrid polyester composite structures reinforced with jute/hemp fibers were fabricated via the hand layup process, with fiber loadings varying between 30%, 50%, and 70% by volume. Fibers were subjected to alkali solutions (NaOH) containing 3% and 5% alkali in advance of the composites' formation. The impact, flexural, and tensile characteristics of hybrid jute/hemp reinforced polyester composites were investigated via laboratory studies. The composite materials that underwent testing with a 50 vol% fiber loading and 3% NaOH exhibited the maximum tensile strength (26.6 MPa), tensile modulus (733.56 MPa), flexural strength (62.7 MPa), and flexural modulus (3.04 GPa).Highlights Hybrid polyester composite structures reinforced with jute/hemp fibers were fabricated. Hand layup method used with various fiber loadings (30%, 50%, and 70% by volume). Highest mechanical properties were obtained for 3% NaOH treatment and 50% fiber loading.

“…The study reported that fibers' hybridization keeping flax as the core layer and kevlar as an outer layer, exhibited improved flexural properties among all the sequences. Karaduman et al 16 studied the effect of layering sequences of jute (J) fibers on the mechanical performance of epoxy‐based composites. Different layering sequences were used by keeping the fiber's orientations 0°, 30°, 45°, and 90°.…”

In the current research investigation, jute and sisal intra‐hybrid woven fabric were specifically tailored to maintain jute and sisal in weft and warp directions, respectively. Jute sisal intra‐hybrid composites were prepared with four layers of intra‐hybrid woven fibers using a compression molding technique. Physical, mechanical (static and dynamic), and thermal stability behavior were investigated, and their structure–property relationship has been established. The obtained results showed that jute‐sisal cross‐interplay‐based hybrid composites recorded maximum tensile and flexural modulus values with minimum anisotropy. It can be concluded from the current experimental investigation that weft/warp orientation and stacking sequence play a significant role in defining the mechanical performance and anisotropic nature of woven fiber‐reinforced laminated composites. Also, the anisotropic properties can be minimized by investigating the effect of fiber orientation and hybridization of natural fibers‐based laminated composites.Highlights Woven mats were tailored to orient different fibers in warp and weft directions. The influence of the fiber's orientation and stacking sequence was analyzed. Fiber orientation and hybridization have influenced mechanical performance. The alternative stacking sequence has shown the highest mechanical properties.
