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

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