    Abstract: An improved slurry formulation for the production of a thermal and environmental barrier coatings are provided which can withstand high temperature applications. The slurry includes a combination of a coarse ceramic powder fraction having close porosity particles and a fine ceramic powder fraction. The combination of the two powders produces a bimodal particle size distribution having a controlled amount of closed porosity that imparts desirable properties to the coating produced. The finer solid particles are interdispersed within an aqueous binder to produce a ceramic matrix with sufficient mechanical strength. The closed porosity containing coarse particles are embedded within the resultant ceramic matrix and do not disintegrate under high temperature conditions to impart a temperature resistant, non-collapsing closed porosity to the coating which can also act as an environmental barrier.

  • Patent number: 9091067
    Abstract: A structured-core laminate panel can be made in an efficient, structurally sound manner without the use of adhesives (film or liquid forms) using materials with different melt or glass transition temperatures. In one implementation, a manufacturer positions one or more resin substrates about a structured core, which comprises a relatively high melt or glass transition temperature compared with that of the one or more resin substrates. The manufacturer heats the assembly to at least the glass transition temperature of the resin substrates, but not to the melt or glass transition temperature of the structured core. This allows the one or more resin substrates to melt and bond (mechanically, chemically, or both) to the structured core on one side (or inner surface), while maintaining a substantially planar or original conformation on an opposing side (or outer surface).

  • Patent number: 8999481
    Abstract: Thermal shock resistance of a ceramic honeycomb structure is increased through modifications of the cell wall joints. Wall joints can be modified such that a longitudinally-extending opening is created, putting two or more cells that meet at the wall joint in fluid communication through such opening. In such a case, all walls that meet at such a modified joint must join at least one other wall at that joint. Alternatively, wall joints can be modified by providing stress concentrating notches which extend into the joint from two or more cells that share the joint.

  • Patent number: 8979014
    Abstract: To reduce sound emission and at the same time improve stability, a multilayer board for acoustic insulation is proposed that includes, but is not limited to a core sheet arranged between a first and a second covering layer. At least one of the two covering layers is of a closed design. The core sheet is firmly connected in a planar fashion to the covering layers. The core sheet comprises slits that extend within the core sheet in the direction of the core sheet thickness, which slits reduce the shear stiffness of the board and thus ensure an improved acoustic insulation effect. On both sides the core sheet comprises continuous edge zones, which extend parallel to the covering layers. An aircraft can have an interior lining formed by panels that comprise the multilayer boards in order to provide acoustic insulation.

  • Publication number: 20150072103
    Abstract: Implementations described and claimed herein include methods of manufacturing related to a spaced array of individually formed void cells, which are linked together. The void cells are protruding, resiliently compressible cells manufactured by thermoforming, extrusion, injection molding, laminating, and/or blow molding processes. The individual void cells are molded and arranged in an array. A separate, porous binding layer is attached to the individual void cells in the array. In one implementation, two arrays may each comprise of linked individually formed void cells, wherein each array is aligned with the other array, and linked individually formed void cells of one array are positioned opposite the linked individually formed void cells of the other array, sharing the same binding layer. In another implementation, multiple arrays can be stacked upon one another. In another implementation, the linked individually formed void cells have substantially different force-deflection characteristics.
