Abstract
A method of fabricating a composite material including a matrix reinforced by ceramic fibers which are derived by ceramization of an organometallic precursor. The method includes the steps of irradiating the ceramic fibers with electromagnetic radiation of wavelength less than or equal to the wavelength of x-rays, and then impregnating or infiltrating a preform made of the irradiated ceramic fibers with a matrix forming material to form the composite. The method provides fibers and hence a composite material with improved mechanical behavior.
