Effectiveness of Nanosilica on Enhancing the Mechanical and Microstructure Properties of Kenaf/Carbon Fiber-Reinforced Epoxy-Based Nanocomposites

With an ultrasonic frequency of 15 kHz and 850 W power capacity, the effects nanosilica particle inclusion on tensile, flexural, impact properties woven fiber-reinforced kenaf/carbon fiber/epoxy hybrid composites were explored experimentally. The nanoparticles dispersed uniformly in epoxy using probe. Test samples made according to ASTM requirements for three distinct weight compositions particles (1, 1.5, 2 wt%). utilizing compression moulding process with following parameters: (i) ratio nanosilica, (ii) length kenaf fibers, (iii) number carbon fiber layers achieve objectives above. According unmodified samples, a concentration 1.5 wt%, tensile strength improved by 31%, flexural increased 42.36%, 22.65%. It was established that interaction micro silica fiber, which interfacial tension, had substantial mechanical water retention capabilities. wt% absorbs less moisture than 1 composites. A scanning electron microscope used examine fractured surface tested nanocomposites.
