| Abstract: | Nano ferrum particle, average 30 um in diameter, was dispersed into polycarbosilane (PC) homogeneously by ultra-sonic method and subsequently mixed silicon carbide ceramic fiber, with good mechanic properties and continuous controllable resistivity, was prepared by melt spinning, curing treatment and sintering. The tri-layer structure microwave absorber composed of the mixed SiC fiber and epoxy resin has good microwave-absorbing properties. The form of nano ferrum particle in ceramic fiber was studied by X-ray diffraction analysis. |
