Abstract
A method for dispersing single walled carbon nanotubes (SWNTs) in epoxy has been investigated. Arc-produced SWNTs were dispersed in bisphenol A epoxy resin and triamine hardener with the aid of a surfactant and high power ultrasound. The quality of dispersion was measured using SEM images of fracture surfaces. The objective was to produce carbon nanotube reinforced epoxy which could then be used in filament winding. The quality of dispersion was found to be highly dependent on the specific dispersion method followed. Clumps of nanotube ropes have been reduced and separated into individual ropes consisting of bundles of roughly 20 nanotubes across the diameter. Composite rings were filament wound with carbon fibers and epoxy containing dispersed nanotube ropes at a concentration of 1-wt%. The rings were tested in compression transverse to the fibers and it was found that the nanotubes did not affect the compressive strength of the composite.
