REMOVABLE MANDREL FOR AUTOMATING PROCESS TO MANUFACTURE CERAMIC COMPOSITE NUCLEAR FUEL CLADDING TUBES
The method described herein uses a ceramic precursors and controlled temperature rises for forming a stiffened ceramic composite fiber matrix to form a ceramic composite fuel cladding tube of the desired geometry and for removing a mandrel about which the composite fiber matrix was formed. The method described herein allows the manufacture of elongated ceramic composite claddings where the mandrel used to define the geometry of the cladding is easily removed without damaging the ceramic composite cladding. The method includes covering ceramic fibers with a mixture comprising at least one precursor of a ceramic material, wrapping the precursor covered fibers around a mandrel, heating the precursor covered fibers to the decomposition temperature of the precursor to convert the precursor to the ceramic material, and heating the mandrel to at least the melting point thereof to remove the mandrel.
