Method for producing sized, coated ceramic fibers

摘要

The present invention provides a method for producing sized ceramic fibers, such as silicon carbide and silicon oxycarbide, by coating with an acrylate-based non-aqueous sizing composition. The fibers may also be coated with interfacial coatings. Some interfacial coatings are moisture-reactive. The sizing protects the fiber and interfacial coatings from moisture and mechanical damage during winding and weaving. The sizing can subsequently be removed in an inert environment at low temperature.
