A method for forming a ceramic matrix composite article includes laying up (410) a first group of plies; laying up (412) a second group of plies, the first and second groups of plies being adjacent to each other; compacting (414) the first group of plies and the second group of plies in the same…
Provided is a bonded compact which is a fired compact comprising a plate-like substrate having hole portions and a film bonded on each bonding surface of the substrate, charcterized in that a raion (T1/L1) of a thickness (T1) of a thinnest portion of the substrate to a maximum length (L1) in a…
Provided is a solid oxide fuel cell having a service life of approximately 90,000 hours, a level required to encourage the widespread use of SOFC. The solid oxide fuel cell is provided with a solid electrolyte layer, an oxygen electrode layer provided on one side of the solid electrolyte layer, and…
Provided are: a porous electrode substrate which has excellent handling properties and surface smoothness and satisfactory gas permeability and electrical conductivity, and enables the reduction of damage to a polymer electrolyte membrane when integrated into a fuel cell; and a process for…
A laminated sintered body is produced having a ceramic porous body 8 having a thickness of 300 mu m or larger and a ceramic dense body 9 having a thickness of 25 mu m or smaller. A green body 5 for the porous body and a green body 3 for the dense body is laminated to obtain a laminate, which is…
A porous ceramic substrate structure (10) having an interior portion (12) formed with an outer surface (14) is porous to at least one selected gas (16). A first ceramic coating layer (18) is applied to the outer surface (14) of the ceramic substrate structure (10) in a suspension state. The first…
An actively-cooled, fiber-reinforced ceramic matrix composite thrust chamber (10) for liquid rocket propulsion systems is disclosed having internal trapezoidal-shaped cooling channels (12). The thrust chamber (10) consists of an inner wall (11), which is fully integrated to an outer wall (14) via…
There is provided a method of creating a carbon to metal connection (16) by placing a portion of a carbon material (12) onto a metal material (14) at a location where a thermal or electrical contact is desired and then joining the carbon material (12) and metal material (14), thereby creating a…
