Interpulation of Mechanical Properties of Polyvinylpyrolidone Surfacetant Assisted Nano Composite Laminates

Dyava Vishnu Vardhan Reddy

The present study focuses on Fabrication and evaluation of mechanical properties of Surfactant (PVP-10) assisted Glass Fiber Reinforced polymers (GFRPs) packed with Low specific Multi-Walled Carbon Nano Tube (MWCNT) contents. The MWCNTs Reinforced GFRP laminates finds more potential applications in the fields of Radar Absorbing Structures (RAS) and sports instruments. In generally, the matrix system (Epoxy) in the Polymer Composite Laminates is modified with Nano-Fillers; namely, CNTs and CNFs (Carbon Nano Fibers) to increase strength of composite. In this study, the GFRP laminates are modified with 0.3%, 0.6%, 0.9% and 1.2% MWCNTs by Weight to escalate the mechanical properties; such as Tensile, Flexural, and Fatigue and also add considerable amount of Surfactant (PVP-10) for better homogeneous dispersion of MWCNTs in the epoxy system. The Fabrication and Testing methods are followed as per ASTM standards. The Tensile, Flexural tests were conducted for both with and without Surfactant assisted GFRP/MWCNT Composite Laminates. The Morphology of The Nano Composites, Delaminating mechanisms and Fiber-Matrix interfacial effects are perceived through Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM).
