Abstract
Disclosed herein are methods of curing silicon carbide precursor polymer fibers, such as polysilazanes, using moisture and free radical generators, such as peroxides. Also disclosed are methods of forming, curing, and using silicon carbide precursor polymers that contain alkenyl groups and free radical generators, such as peroxides.
