Effects of Single Wall Carbon Nanotubes on Interlaminar Shear in GRP Panels

Abstract

This report summarizes the testing of glass reinforced plastic (GRP) panels consisting of 24-ounce woven roving e-glass and vinylester. The center two plies of woven roving of each panel have been treated with varying amounts of carbon nanotubes. The purpose of incorporating the carbon nanotubes is to increase the interlaminar shear strength of the composite panel. The Short Beam Shear test was used as a quick screening method to determine the effect of single wall carbon nanotubes (SWNTs) on interlaminar shear strength. It was found that the single walled carbon nanotubes caused a decrease in the interlaminar shear strength for this material system. The decrease in shear strength may be due to a problems with the functionalization of the SWNTs or due to the SWNTs trapping free radicals resulting in incomplete cure.
