Carbon fiber coating with polymer preceramic precursors is an easy, inexpensive, and reproducible method of protecting carbon fibers against chemical and mechanical hazards (see Figure for a roving of HT carbon fibers coated with polysiloxane and calcined). Polysilazane Kion VL 20 was found to be superior to polysiloxanes because it makes coatings insensitive to drying and curing conditions; also, their tensile strength increases with coating thickness.
