Influence of Epoxy/Nanosilica on Mechanical Performance of Hemp/Kevlar Fiber Reinforced Hybrid Composite with an Ultrasonic Frequency

Abstract

Ultrasonic vibration was employed in blending the nanosilica into epoxy resin to manufacture hemp/kevlar/nanosilica-based epoxy composites, with an ultrasonic occurrence of 20 kHz and a 900 W capacity of power. An ultrasonic probe was utilized to ensure the consistent dispersion of the nanoparticles in the epoxy. The mechanical characteristics of hemp/kevlar fiber reinforced with epoxy/nanosilica in a mat form have been studied. Hand layup procedures were used to create these composites, including varying weight % of nanosilica and variable fiber stacking sequencing. The different weight % are 3, 6, and 9, and the stacking sequences are B, C, and D. The effectiveness of ultrasonic irradiation on mechanical characteristics was investigated and related. The inclusion of 6 wt.% of SiO2 to the B type resulted in a 25% rise in tension and a 37% in bending. The addition of 6 wt.% silica to the C-type hybridization nanocomposite results in a 34% rise in tension and a 38% rise in bending. Extreme tension behavior is attained at 6 wt.% SiO2 with epoxy with the B type piling order, and extreme bending behavior is obtained at 6 wt.% SiO2 with the C type piling order. A B-type model composite with a 6-wt.% SiO2 addition performed better in hygroscopic than A, C, and D type model composites. An SEM is utilized to observe the microstructure of shattered materials.

Biosynthesis of Iron Oxide Nanoparticles Using Leaf Extract of Ruellia tuberosa: Mechanical and Dynamic Mechanical Behaviour Kevlar-Based Hybrid Epoxy Composites

“…Investigations have indicated that it should be used as a metal replacement because it is nearly significantly more powerful. Once crocheted as well as knitted with a 50% structure of Kevlar as well as polypropylene fabrics, the compounds demonstrated significantly greater cut tension indicator, suitable for use in activewear as well as medical uses [ 28 , 29 ]. Numerous studies and research have been conducted on the advancement of Kevlar in protective gear uses as well as the optimization of the requisite material properties.…”

Effect of Packaging Materials and Moisture Level on Pearl Millet Stored Under Ambient Condition

“…The moisture content of grains stored in polythene bag at 12% initial MC were 12.40, 13.40 and 13.93%, respectively at 50, 100, 150 and 200 DAS and it was statistically at par to those of millets stored in metal container or polythene bag with 12% initial MC (Fig. 1) [23][24][25]. When seed could be packaged in moisture proof containers, the relative humidity of the air around the seed remains low, then the seed equilibrium moisture remains low [26,27].…”

Jute-basalt reinforced epoxy hybrid composites for lightweight structural automotive applications

“…Hybrid composites are considered to offer structures with a balanced effect from the used fibers by retaining the advantages of these fibers and decreasing some of their disadvantages. [29][30][31][32] Hybrid composites are gaining significant popularity because they can be easily tailored to provide superior characteristics which cannot be reached with one fiber reinforced composite. 5 The shortcomings of weak fibers can be overcome by hybridization with stronger fiber since it can improve the strength, stiffness, and moisture resistance of the composites.…”
