Abstract
Conventional carbon fiber polymer exhibit low interlaminar fracture toughness. Carbon nanotubes (CNTs) are exceptional candidates to act as reinforcement of carbon fibers (CF) in composite materials. CNTs can increase the interfacial surface between fibers and matrix improving exponentially the adhesion. Therefore, enhanced the mechanical properties of the entire material. Charger salts are usually introduced to the dispersion in order to improve adhesion of CNTs to substrate and increase the deposition rate. The aim of this experiment is to investigate the deposition of CNTs on the CF. Effect of functionalized and un-functionalized CNT and different salts on the deposition of CNT on CF were investigated. Result shows that high amount of functionalized CNT were deposited on CF compared to pristine CNT. Addition of sodium hydroxide salt improved the adhesion of CNTs and increased the deposition rate on CF surface than magnesium nitrate salt. Epoxy composites produced by CNT/CF using different salts indicates that addition of salt does not really influence the properties of composites materials.
