| 20090230353 | FIBER AGGREGATE AND FABRICATING METHOD OF THE SAME - A fiber aggregate contains fine carbon fibers and fine boron nitride fibers. Desirably the boron nitride fibers form an outer layer portion of the fiber aggregate and the fine carbon fibers form a core portion of the fiber aggregate. Desirably the fine carbon fibers and the fine boron nitride fibers are twisted with each other. Desirably the fine carbon fibers are carbon nanotubes and the fine boron nitride fibers are boron nitride nanotubes. Desirably the fiber aggregate further contains boron-containing fine carbon fibers. The fine boron nitride fibers are formed by substituting carbon atoms of fine carbon fibers by boron atoms and nitrogen atoms. The fiber aggregate is fabricated by mixing a fiber aggregate that contains fine carbon fibers with boron and heating the fiber aggregate mixed with the boron in a nitrogen atmosphere to transform some of the fine carbon fibers into fine boron nitride fibers. | 09-17-2009 |

| 20110315920 | PROCESS FOR PREPARATION OF NANO CERAMIC-METAL MATRIX COMPOSITES AND APPARATUS THEREOF - A method to introduce ceramic particles into the liquid metal from the polymeric precursor route by in-situ process by cross-linking organic precursor into a hard polymer, this powder is crushed, and then added to the liquid melt for in-situ pyrolysis of the organic into the ceramic phase. The starting material, the organic, for the above process can be in the form of a liquid or a solid. If it is a solid it us usually dissolved into a solvent to create a liquid form. The organic is then cross linked either directly by a thermal process, by adding a catalyst, or by the well known sol-gel process into a hard polymer. It is this hard polymer which is then pyrolyzed into the high temperature ceramic material by the process outlined above. | 12-29-2011 |
