Development of Polymer-Derived Ceramic Fibers

Abstract

Polycarbosilane is a representative pre-ceramic polymer for preparing SiC ceramics, for example, Hi-Nicalon fiber and Tyranno Fiber. Furthermore, oxide or nitride ceramics can also be produced from the polycarbosilane by firing in air or ammonia, respectively. We developed highly heat-resistant SiC fibers and photocatalytic fiber by improvement of pre-ceramic polymer and production process.These fibers contribute to the environmental purification as the important material for diesel particulate filter (DPF), high efficiency gas turbine or decomposition system for harmful organic substances in water.
