    Abstract: A method and system for fabricating a composite structure is disclosed. A composite preform (10) has an upper surface (14) and an opposing lower surface (15). The upper and lower surfaces (14, 15) each define a preform major surface. A heat sink (120) is located in proximity to one of the preform major surfaces so as to extend across only a portion (16) of the composite preform (10). A resin is cured in the composite preform (10) to form the composite structure. The resin cures exothermically. During curing of the resin, heat is conducted away from the portion (16) of the composite preform (10) into the heat sink (120).

  • Patent number: 8431061
    Abstract: A method for use in manufacturing a ceramic matrix composite article includes assembling a ceramic fiber sheet between a tool and a die, where the tool is conformable to the shape of the die and the melting point of the die is greater than the melting point of the tool. The assembly is then heated to soften the tool. At least one of the tool, the die or a separate inflatable member is then pressurized to conform the tool and the ceramic fiber sheet to the die. Next, the assembly is cooled and the pressure is vented before removal of the tool and ceramic fiber sheet from the die. A preceramic resin with a catalyst is then applied to the ceramic fiber sheet and cured at a curing temperature that is below the melting point of the tool, to form a preform. The tool is then removed from the preform.

  • Patent number: 8394307
    Abstract: A Method for manufacturing a liquid discharge head having a flow path forming member for forming a liquid flow path which communicates with a discharge port discharging liquid, comprises; preparing a layer containing a compound having a structure represented by Formula (1) and a structure represented by Formula (2) as a main chain on a substrate, providing a solution in which a resin is dissolved in a compound represented by Formula (3) or (4) on the layer, forming a mold having the shape as the flow path from the resin, providing a layer which will become the flow path forming member so as to cover the mold, and removing the mold to form the flow path.

  • Patent number: 8394224
    Abstract: Layered nanostructures are constructed by imprinting material with a mold, while selectively modifying and removing a portion of the mold. The mold, which includes a pattern of features, is modified so that the portion of the mold that includes the features is made chemically and/or physically distinct from the rest of the mold. That portion of the mold that includes the features is retained while the rest of the mold is removed. The retained portion of the mold provides mechanical support for any adjoining layer or layers.

  • Patent number: 8323549
    Abstract: A method for forming temporary protective coatings and bondable surfaces is disclosed. In the method, a soluble layer is disposed on a material surface, such as the interior surfaces of cell walls of a web material. The soluble material is then removed or leached from the web material to form and expose a roughly textured, bondable surface for bonding with another material, such as AVCOAT insulation. Use of the soluble layer, therefore, enhances the bondability of any surface that requires good adhesion, such as where the surface is difficult to reach for conventional surface preparation techniques.

  • Patent number: 8303883
    Abstract: The invention provides foams of desired cell sizes formed from metal or ceramic materials that coat the surfaces of carbon foams which are subsequently removed. For example, metal is located over a sol-gel foam monolith. The metal is melted to produce a metal/sol-gel composition. The sol-gel foam monolith is removed, leaving a metal foam.

  • Patent number: 8241540
    Abstract: A method of manufacturing a liquid discharge head including a flow path member for forming a flow path communicating with a discharge port discharging a liquid includes forming a mold of the flow path made of a positive photosensitive resin on a substrate; applying a coated layer on the mold for forming the flow path member, which coated layer includes a solvent, an epoxy resin, and a curing agent of the epoxy resin; removing the solvent from the coated layer at a normal temperature under substantially 1 atm. so that the weight of the coated layer may become 93% or less of that thereof at a time of applying of the coated layer, and then further removing the solvent from the coated layer under a depressurized condition; curing the coated layer; and removing the mold to form the flow path.
