<p>A method of coating a fiber resulting in a more oxidative resistant fiber. The method comprises mixing metal alkoxides and basic metal carboxylates in amounts such that the metal alkoxides are substantially water soluble. The basic metal carboxylate has the formula: R min -CO2M min (OH)n. zHm X where (i) R min is an organic radical; (ii) M min is any metal that has a valence of 3 or 4; (iii) x is BO3<->, SO4<=>, Cl<->, NO3<->, R sec CO2<->, where R sec is an organic radical; (iv) n and m correspond to the valence of (M min -1) and x respectively; and (v) Z has a value sufficient so that said R min -CO2M min (OH)n is substantially water soluble. A layer of the solution is applied to the fiber and the fiber is exposed to a temperature sufficient to form an oxide surface. The fibers can be used to make polymeric composites. Fibers having the above-described coating are impregnated with a resin, stacked in layers and exposed to pressure and optional heat.</p> |
