  • Patent number: 11046620
    Abstract: A method of processing a CMC component includes applying a surface formulation comprising a resin and/or a preceramic polymer to a fiber preform. The surface formulation is cured to form a surface coating, which is then pyrolyzed to convert the resin to carbon and/or the preceramic polymer to silicon carbide. After pyrolysis, the fiber preform is infiltrated with a melt comprising silicon to form a CMC component. During melt infiltration, the carbon reacts with the silicon to form silicon carbide, and the silicon carbide prevents unreacted silicon from accessing a surface region of the CMC component. Thus, after melt infiltration, a concentration of free silicon in the surface region is a low amount of about 5 vol. % or less. Upon assembling the CMC component with a metal component, diffusion between the components is inhibited or prevented by the low amount of free silicon in the surface region.

    Abstract: A method for fabricating a cellular tritium breeder component includes obtaining a reticulated carbon foam skeleton comprising a network of interconnected ligaments. The foam skeleton is then melt-infiltrated with a tritium breeder material, for example, lithium zirconate or lithium titanate. The foam skeleton is then removed to define a cellular breeder component having a network of interconnected tritium purge channels. In an embodiment the ligaments of the foam skeleton are enlarged by adding carbon using chemical vapor infiltration (CVI) prior to melt-infiltration. In an embodiment the foam skeleton is coated with a refractory material, for example, tungsten, prior to melt infiltration.

  • Patent number: 9676631
    Abstract: A process for producing reaction bonded silicon carbide (RBSC) from high purity, porous, essentially all-carbon preforms through contacting said preforms with silicon metal at room temperature, and subsequently heating to melt silicon metal and cause infiltration into said preform causing reaction to silicon carbide and leaving residual silicon, to result in a dense silicon carbide-silicon composite. The process offers the ability to produce RBSC with higher purity, higher strength, and lower cost as long as the carbonaceous preforms are of sufficient purity and pore size distribution to allow for uniform, crack-free bulk bodies to be fabricated.

  • Patent number: 8906284
    Abstract: A wrinkled adhesive surface is prepared by swelling a laterally confined elastomer layer with a polymerizable monomer composition. Swelling the elastomer layer spontaneously produces a wrinkled surface, and the wrinkles are then stabilized by polymerizing the polymerizable monomer composition. The stabilized wrinkled surfaces prepare by the method can exhibit substantially enhanced adhesion relative to smooth surfaces of the same material. The stabilized wrinkled surfaces can also exhibit adhesion that is repeatable through many cycles of contact with and separation from another surface. The adhesive characteristics of the stabilized wrinkled surfaces can be tailored by manipulating the size of the wrinkles.

A process for producing the encapsulating material for solar cell in which dialkyl peroxide (A) and an organic peroxide (B) selected from peroxycarbonate and peroxyketal at a ratio by weight of 10/90 to 90/10 of (A) and (B) in a liquid state impregnate the molded form of the ethylene copolymer is a preferable embodiment of the present invention.

  • Patent number: 8343395
    Abstract: A powder particle shaping device includes a closed cavity capable of changing between multiple shapes as an external pressure changes, and the closed cavity compresses and moves powder particles with which the closed cavity is filled full while the shape changes. A powder particle shaping method is further provided, which includes a. filling a cavity full with powder particles to be shaped; and b. applying a varying external pressure to make the cavity change repeatedly between multiple shapes, thereby making the powder particles under compression move and be subject to friction, where the cavity is kept in a closed state during an effective processing process. The shaping device and method have highly controllable shaping processing intensity of powder particles and stable processing strength, and thus are applicable to shaping and pulverization of various powder particles, and also applicable to pulverization and further shaping processing of dispersed agglomerates.

  • Patent number: 8318059
    Abstract: The present invention provides a method for producing a medical device, preferably an ophthalmic device, more preferably a contact lens, made of a stabilized poly(oxyalkylene)-containing polymeric material. The method of the invention comprises the steps of: curing, in a mold, a composition comprising (a) a prepolymer having at least one poly(oxyalkylene) unit, (b) a biocompatible organic multi-acid or biocompatible salt thereof in an amount sufficient to improve the stability of the poly(oxyalkylene)-containing polymer made from the composition, (c) optionally a photoinitiator or a thermal initiator, and (d) optionally one or more vinylic monomers, to form the medical device being less susceptible to oxidative degradation; and removing the medical device from the mold.

  • Patent number: 8303875
    Abstract: A method for producing a vinylidene fluoride resin film having excellent transparency, weather resistance, chemical resistance, break resistance and formability is provided. The film is shaped by sandwiching a vinylidene fluoride resin in a molten state between rollers or metal belts so as to let them cool down, thus realizing polyvinylidene fluoride with a fine average spherocrystal diameter. Thus, the vinylidene fluoride resin film having the above-stated properties can be obtained.

  • Patent number: 8298460
    Abstract: The invention relates to a method for granulating and crystallizing thermoplastic polymers, the granules being contained in a liquid after granulation of a polymer melt and the granules being nucleated in the liquid once the pressure of the liquid is increased and the temperature of the liquid is increased, and the granules being crystallized in the liquid once the pressure of the liquid is again increased and the temperature of the liquid is again increased. According to the invention, the granules are removed from the liquid once the pressure and the temperature of the liquid containing the granules have been reduced.
