Carbon Nanotubes as Fillers Toru NOGUCHI Akira MAGARIO Development Center Nagano, Nissin Kogyo Co., Ltd., Nagano, Japan Hitoshi IWABUKI Kazuya NAGATA Material Technology Department, Industrial Technology Center of Okayama Prefecture, Okayama, Japan Nippon Gomu Kyokaishi,(2005),78(6),205-210 General Review in Japanese Abstract Carbon nanotubes (CNTs) have been drawing much attention as fillers for composites because they have extraordinarily high strength, elastic moduli, flexibility and aspect ratios as well as superior electrical and thermal properties. In this article, author review the studies on composites fabricated with CNTs and resin, metal or elastomer matrices including the latest researches on CNT-filled aluminium composites and elastomer composites. When CNTs were uniformly incorporated in elastomers, isotropic enhancement in their tensile strength and moduli were observed. The flow phenomena at high temperatures disappeared in non-cured rubber matrix composites and thermoplastic elastomer matrix composites with uniform CNT dispersion. These CNT reinforcements are thought to be applicable for producing high efficiency rubber products and their recycling.
