ABSTRACT:
A novel composition comprising a metal or ceramic matrix material includes a reinforcing system of hollow, similarly aligned carbon-coated ceramic fibers which provide high strength, increased creep resistance and a significant reduction in weight. Also disclosed is a novel structural component incorporating the reinforcing system of hollow fibers to provide a mechanism enabling fluids or gases to pass or be injected through the element fibers for cooling or other functions. A method for fabricating the hollow fiber-reinforced component is also disclosed. Various applications for the fiber-reinforced structural component are also disclosed.
