Investigation of Dynamic Mechanical Behavior of Nanosilica Filled Carbon-Kevlar-Epoxy Polymer Hybrid Nanocomposite

Reinforcement of epoxy-carbon-Kevlar fabric composite with the addition nanosilica has resulted in evolution new hybrid polymer nanocomposite, which results improved mechanical properties nanocomposite. The current investigation concentrated on dynamic behavior unfilled and filled carbon-Kevlar-epoxy five four layers carbon Kevlar woven fibers respectively epoxy matrix (5C4K). Nanosilica was mixed into at different weight percentages (wt.%) 0, 0.5, 1.0, 1.5. laminates were fabricated using vacuum-assisted resin infusion moulding (VARIM) technique. properties, storage modulus, loss damping factor (tan delta), glass transition temperature investigated a dynamic-mechanical analyzer ranging from 25 to 165 degrees Celsius. test specimens prepared accordance ASTM D4065 standard investigate analysis (DMA) tested for behaviors nanocomposites are very much influenced by presence nanosilica. modulus added composites more than ones delta) observed an composite.
