| Abstract: | The shaped silicon carbide fibers were prep ared from polycarbosilane by melt spinning,curing treatment and sinterin g. The effects of spinning temperature, spinning pressure and drawing ve locity on the degree of profile and effective diameter of the fibers were studied and the preparation technology was determined. The structu ral radar absorbing materials composed of the fibers and epoxy resin have good radar absorbing properties. |
