Abstract:
A method of producing a sized ceramic fiber, wherein the method comprises the steps of:1) applying to a ceramic fiber selected from silicon carbide fibers, silicon oxycarbide fibers, silicon oxynitride fibers, silicon carbide fibers containing titanium, silicon oxycarbonitride fibers, and silicon nitride fibers; a non-aqueous sizing composition consisting essentially of(a) 1 to 98% by weight of a sizing compound selected from the group consisting of multifunctional acrylate monomers, multifunctional methacrylate monomers and multifunctional acrylate polymers;(b) 1 to 20% by weight of a curing agent selected from the group consisting of ultra-violet photoinitiators and free-radical initiators; and(c) 1 to 98% by weight of a dry solvent; and2) curing the sizing compound to form a sized ceramic fiber.
