“…As a most viable choice for an environmentally acceptable and sustainable reinforcement, natural fibers have been introduced and extensively investigated. [2][3][4][5] Research and development on natural fiber-reinforced composites (NFRC) have produced highstrength materials that have the potential to replace their synthetic counterparts. Recently, the scientific community and industries have been focusing on hybridizing natural fiber-based polymer 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.

“…The controllability of high heating rates shown in most studies allow for significant cycle time reduction and an increase in mechanical properties. Naik et al [106] discuss that these properties ensures that it is economically viable, particularly in aerospace. It will likely take industry a lot longer to adopt over existing methods due to cost and required technical know-how to ensure high quality parts are produced.…”

“…It was found in our previous studies that microwave heating is an effective method to accelerate the reaction rate by largely improving the heat transfer efficiency . Microwave is an electromagnetic wave with a frequency range from 300 MHz to 300 GHz, and its heat transfer is mainly through the activation of the dielectric loss of polar units in molecules, which is more effective yet significantly different from conventional heat conduction. , As early as the 1990s, microwaves were used for organic synthesis . In recent years, studies on the application of microwave heating in the synthesis of cellulose esters were mainly with heterogeneous systems.…”

The acylation modification of cellulose to make it processable is an important method to utilize this green, renewable material with broad prospects. However, it usually takes several hours or even more than 20 h to obtain products with a high degree of substitution (DS) through the methods reported in the existing literature, especially for cellulose acetate (CA). In this study, rapid homogeneous acylation of cellulose is achieved in a novel CO 2 switchable solvent system by using microwave heating. CA products with DS ranging from 1.83 to 2.91 can be obtained within 3−15 min by using acetic anhydride as the acylation reagent. This strategy can also be applied for the synthesis of a series of cellulose esters with different side chain lengths, and it takes only 10 min to produce cellulose esters with a DS higher than 2.20 under microwave heating. This study suggests a facile and effective method for the synthesis of cellulose esters.
