Solid state draw a laminated polymer billet containing two or more polymer compositions laminated to one another to prepare an oriented polymer composition.
STRONGLY SCATTERING CERAMIC CONVERTER AND METHOD FOR PRODUCING SAME
A strongly scattering optoceramic converter material having a density of less than 97% is provided, as well as a method for producing such an optoceramic material. By appropriately choosing in particular the composition, blending method, and sintering conditions, the production method permits to produce converter materials with tailored properties.
Bead foam compression molding method with in situ steam generation for low density product
Disclosed is a method for molding a foamed article, such as a midsole or outsole for footwear, in which first water, then a desired amount of thermoplastic polyurethane foam beads are placed in a compression mold in the shape of the article and the mold is brought to a peak temperature of from about 130° C. to about 180° C. over a period of from about 300 to about 1500 seconds, then cooled to from about 5° C. to about 80° C. over a period of from about 300 to about 1500 seconds within about 30 seconds after the peak temperature is reached. The foamed article made by the method has a density of from about 0.1 to about 0.45 g/cm.sup.3.
Pressureless sintering-based method for making a two-phase ceramic composite body
Inventive manufacture of CrB.sub.2—Al.sub.2O.sub.3 composites is based on pressureless sintering. According to typical inventive practice, CrB.sub.2 powder and Al.sub.2O.sub.3 powder are mixed together in selected volumetric proportions so that the volume of the CrB.sub.2 does not exceed 50% of the overall volume of the CrB.sub.2—Al.sub.2O.sub.3 mixture. The CrB.sub.2—Al.sub.2O.sub.3 mixture is shaped into a green body. The green body is pressureless sintered in a non-oxidizing atmosphere at a firing temperature in the approximate range between 1600° C. and 2050° C. The present invention succeeds in preparing, via pressureless sintering, a proportionality-associated range of compositions in the CrB.sub.2—Al.sub.2O.sub.3 system, which is a potentially “advanced” ceramic system. A typical inventively fabricated CrB.sub.2—Al.sub.2O.sub.3 composite is inventively configured in a complex shape, and has “advanced” material (e.g., mechanical) properties that are favorable for a contemplated application. Inventive manufacture of ceramic-ceramic composites is thus dually attributed, and uncommonly so, with complex shape-ability and advanced capability.
MICROLATTICE DAMPING MATERIAL AND METHOD FOR REPEATABLE ENERGY ABSORPTION
Described is a micro-lattice damping material and a method for repeatable energy absorption. The micro-lattice damping material is a cellular material formed of a three-dimensional interconnected network of hollow tubes. This material is operable to provide high damping, specifically acoustic, vibration or shock damping, by utilizing the energy absorption mechanism of hollow tube buckling, which is rendered repeatable by the micro-lattice architecture.
Coated articles with microcapsules and other containment structures incorporating functional polymeric phase change materials
An article comprises a substrate, a first functional polymeric phase change material, and a plurality of containment structures that contain the first functional polymeric phase change material. The article may further comprise a second phase change material chemically bound to at least one of the plurality of containment structures or the substrate. In certain embodiments, the article further comprises a second phase change material and a binder that contains at least one of the first polymeric phase change material and the second phase change material. The containment structure may be a microcapsule or a particulate confinement material
Microporous composite sheet material
A moisture vapor permeable, water impermeable composite sheet material is provided which is suitable for use as a housewrap material, and is also useful for other applications such as tarpaulins, or as covers for automobile, boats, patio furniture or the like. The composite sheet material includes a nonwoven substrate and an extrusion-coated polyolefin film layer overlying one surface of the substrate. The nonwoven substrate is comprised of polymeric fibers randomly disposed and bonded to one another to form a high tenacity nonwoven web. The nonwoven substrate has a grab tensile strength of at least 178 Newtons (40 pounds) in at least one of the machine direction (MD) or the cross-machine direction (CD). The extrusion coated polyolefin film layer is intimately bonded to the nonwoven substrate. The film layer has micropores formed therein to impart to the composite sheet material a moisture vapor transmission rate (MVTR) of at least 35 g/m.sup.2/24 hr. at 50% relative humidity and 23° C. and a hydrostatic head of at least 55 cm. In one embodiment, the nonwoven substrate comprises a spunbonded nonwoven fabric formed of randomly disposed substantially continuous polypropylene filaments. The spunbonded nonwoven fabric is an area bonded fabric in which the filaments are bonded to one another throughout the fabric at locations where the randomly disposed filaments overlie or cross one another.
Porous Materials
A porous membrane material comprising a porous membrane substrate coated with a thin, uniform coating of a metal or metal alloy. The membrane material can have high electrical conductivity. The membrane material can exhibit a very high ratio of electrical conductivity to thermal conductivity. The porous membrane substrate may be removed to form the membrane.
Low density composite materials, their production and use
Laminar structures comprising a fiber reinforced layer bonded to an expandable filler containing layer to provide improved flexural stiffness to weight ratio at lower fiber loading; a process for the manufacture of the laminar structures in which the material are selected so that migration of the expandable filler into the fiber structure of the fiber reinforced layer as they expand is minimized or prevented.
