Mechanical characterization of Fiber glass Composites with Nano silica

Abstract

Epoxy-based fiber glass composites with enhanced strength by silica Nano particles checked for mechanical strength by addition of nanoparticles. Fiber glass Composites were prepared with glass fiber and nanoparticles containing resin, by infusion method. proper mixing of nanoparticles in resin was checked by various techniques. Viscosity of liquid resin reduced because of nanoparticles but still have good command to reinforce glass fibers. glass transition temperature (Tg) of polymer containing silica is highly improved at small concentrations. Tensile strength of sample showed more than 20% increase by adding 1mg Nano silica. Tensile properties of composites with higher ratio of nanoparticles is decreased.
