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.

A method of fabricating a composite material comprising a matrix reinforced by ceramic fibers, said method comprising the steps of:
- providing ceramic fibers derived from an organometallic precursor by ceramifying fibers formed from said organometallic precursor;
- irradiating the ceramic fibers by exposure to electromagnetic radiation of wavelength less than or equal to the wavelength of x-rays to improve the mechanical properties of the ceramic fibers;
- and
- densifying a preform made of said irradiated ceramic fibers by impregnating or infiltrating the preform with a material constituting the matrix to obtain the composite material.
