“…Similarly, Figure 2C,D reveal that the hybridization of flax fiber and kenaf fiber increased the tensile strength, tensile modulus, flexural strength, and flexural modulus values by 60.26%, 33.94%, 125.75%, and 82.67% compared with pure PP, and by 31.16%, 5.69%, 66.64%, and 19.72% compared with pure kenaf (wKWK) composites. Similar behavior was reported by Kazi et al [ 18 ] in which roselle‐sisal hybrid composites with roselle fiber in the warp direction and sisal fiber in the weft direction exhibited superior mechanical properties.…”

“…The mechanical properties of composites with woven fabrics are affected by several parameters, including yarn type, fiber content, fiber‐matrix adhesion, and yarn interlocking. [ 18 ] The orientation of the fibers in the longitudinal and transverse directions influences the load distribution between the fibers and, consequently, the ultimate strength behavior of composites. Tests on single fibers revealed that jute and flax fibers have the better tensile strength.…”

“…In addition, the specimen experiences both normal and shear stresses under flexural loading. According to researchers, stress transfer occurs from the warp yarn to the weft yarn [ 18 ] and thus the mechanical properties of fibers vary significantly depending on their orientation.…”

“…Fiber to fiber and fiber to matrix stress transmission are influenced by fiber‐matrix adhesion, yarn interlocking in the fabric, warp/weft fiber type, and their interactions [ 18 ] SEM was utilized to examine the fiber‐matrix bonding in this investigation. Figure 3(A‐H) shows the fractured surfaces (after tensile test) and the arrangement of fibers within the polymer matrix for wSWJ, wJWS, wFWK, and wKWF composites.…”

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.

It is well known that fiber-matrix interface region is crucial to ensure an efficient stress transfer between matrix and reinforcement and that it controls the composite behavior when subjected to external loads. In this experimental study, micro-damage mechanisms of HDPE/surface modified henequen fiber reinforced composites are investigated in tensile quasi-static mode. Two essential parameters of the materials composition were taken as main indicators: fiber length and quality of the fiber matrix adhesion. Essential Work of Fracture theory (EWF) was applied on double edge notch tensile (DENT) specimen geometry. Acoustic Emission (AE) technique was coupled to composite samples to obtain the characteristics of stress waves signals to monitor in real time damage evolution and failure mechanisms detection. Results demonstrated the substantial effect of chemical bonds interaction in the interface area on the composite mechanical properties. The total fracture work (W f ) exhibited an increasing value in both components, W e and W p , in chemically treated fiber composites. Likewise, mechanical properties are reported to be higher by 37% in maximum load in such materials. Elastic waves detected by AE were identified and correlated to micromechanical events during composite damage sequence. Most of the signals corresponded to microcracks (signals of low amplitude, short duration), propagation of microcracks (signals of medium amplitude), fracture of fibers and matrix (signals of long duration and high amplitude). AE signals detected exhibiting higher energy were associated to an enhanced fiber/matrix interface.

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.
