Description
Summary:This research article describes the results of nano-silica (nSiO 2 ) filled epoxy (Ep) mono composites with different contents (0.5, 1.0, 1.5, 3, and 5 wt.%) and carbon fabric-reinforced epoxy (CFE) with 1.5 and 3 wt.% of nSiO 2 hybrid composites and their physical and mechanical properties characterized by different techniques as per ASTM standards. Mechanical mixing and sonication techniques were followed to disperse nSiO 2 into Ep resin. Furthermore, the same nSiO 2 /Ep is reinforced with carbon fabric by hand lay-up followed by vacuum-bagging technique. The morphological features were studied by scanning electron microscopy. The properties of the Ep based mono and hybrid composites showed that the hardness, tensile strength/modulus, and flexural strength/modulus, as well as impact strength of the composites enhanced with nSiO 2 wt.% up to 3 wt.% for mono and hybrid composites and decreased thereafter; suggesting that the beneficial properties ensued up to 3 wt.% nSiO 2 content.
