Abstract
A composite material having a fiber system embedded in a host matrix material. The fiber system has a protective reaction barrier around the embedded fibers to prevent deleterious chemical or mechanical reaction between the fiber and matrix. The fiber coating is applied by immersion of the fiber system into an alkoxide solution of the desired oxide precursor with controlled immersion and withdrawal rates with subsequent drying, heating to convert to a pure oxide state, and where required, post processing, to convert the oxide coating to a carbide or nitride, for example.
