Abstract
A method of fiber preparation for discontinuous fiber-reinforced ceramic matrix composite and a coated discontinuous fiber prepared by this method. The method includes immersing a fiber spool in a resin and drip drying the fiber spool until any excess resin is removed. Next, the damp fiber is cut or chopped and heated to the green-state cure temperature of the resin. After the resin has cured, the product is a coated discontinuous fiber whereby the inner fiber filament bundle is held together by a cured resin shell and the individual filaments are held together by the resin.
