... the sonication cycle was completed, the mixture was then placed in a three roll milling processor for six successive cycles incrementally reduced from 20 to 5 μ m gap spacings at 140 rpm. Epikure curing agent W was then added to the modified resin and mixed using a high-speed mechanical stirrer. To reduce...

... and nanophased carbon/epoxy composites was investigated. Epoxy resin was modified using 1 wt. %, 2 wt. %, and 3 wt. % nanoclay. Carbon/epoxy composites were fabricated by vacuum assisted resin transfer molding process and compared with neat samples with and without exposure to seawater. Nanoclay was dispersed...
