20130334742 | METHOD AND SYSTEM FOR FABRICATING DOME SHAPED LTCC SUBSTRATES - A system for the fabrication of dome shaped low temperature cofired ceramic (LTCC) substrates comprises a plurality of prefired substrates, a first mandrel, and a second mandrel. The prefired substrates may form a stack and each may include a circular central portion and a plurality of segments uniformly distributed along the circumference of the central portion. Each segment may include a first edge, an opposing second edge, and an end edge. The first and second edges each may have an inner end and an opposing outer end. The end edge may be coupled to the outer end of the first and second edges. The first mandrel may have a first circumference and may be configured to receive the prefired substrates while the stack is formed. The second mandrel may have a second circumference smaller than the first circumference and may be configured to retain the stack during a firing process. | 12-19-2013 |

20110187030 | PROCESS FOR PRODUCING SiC FIBER-BONDED CERAMICS - Provided is a process for producing dense SiC fiber-bonded ceramics excellent in heat resistance and having a shape hard to form by hot pressing such as an elongated shape. The process for producing SiC fiber-bonded ceramics composed of: inorganic fiber made of SiC; and interfacial layers mainly made of carbon includes vacuum-sealing a preform, prepared by forming specific silicon carbide-based inorganic fiber into a certain shape, into a capsule and hot-isostatic-pressing the preform. The process is characterized in that the ratio of the number of carbon atoms to the number of silicon atoms in the preform is 1.02 to 1.20, and before the hot isostatic pressing, the preform is heated in an inert gas atmosphere or a reducing gas atmosphere at a temperature of 1200° C. to 1800° C. to adjust the oxygen content in the inorganic fiber to 6.0% by weight or lower, and then the hot isostatic pressing is carried out. | 08-04-2011 |

20090014926 | Method of constructing a hollow fiber reinforced structure - A method of constructing a hollow fiber reinforced structure is disclosed. A spindle structure is provided for defining a preform shape. A resin binder or matrix is applied to a fiber material and the fiber material is placed around the spindle structure to create a hollow preform having a shape defined by the spindle structure. The preform structure is reshaped into a desired shape defined by the interior surface of a hollow mold and the exterior surface of an expandable insert structure. The reshaped preform structure is further conditioned to create a finished part. A hollow filament wound ceramic matrix composite airfoil suitable for use in a gas turbine engine may be constructed using the disclosed method. | 01-15-2009 |
