Thermogravimetric and dynamic mechanical analysis of woven glass/kenaf/epoxy hybrid nanocomposite filled with clay

This research studies the thermogravimetric and dynamic mechanical analysis of woven glass/kenaf/epoxy hybrid nanocomposites filled with clay. Epoxy resin modified with 1.0 wt% silicon is sonicated with varying clay loading of 1.0, 3.0 and 5.0 wt%. The resin is then spread onto alternating woven gla...
