| Abstract: | This paper presents a method of carbon fiber coating with silica fromsol-gel process.Carbon fibers are passed through hydrolytic solution of tetraethoxysiliane(TEOS).which then chemically converted by drying and pyrolysis to form silica coating.The coating was characterized from its morphology,constitution and behavior in C/Mgcomposites fabricated by liduid infiltraion. |

| Keywords: | coating sol-gel metal matrix composite |
