Embodiments of the present invention describe secured fiber-reinforced aerogels and laminate structures formed therefrom. In one embodiment a laminate comprises at least one fiber-reinforced aerogel layer adjacent to at least one layer of fiber containing material wherein fibers from said at least one fiber-reinforced aerogel layer are interlaced with fibers of said at least one fiber-containing material. In another embodiment a laminate comprises at least two adjacent fiber-reinforced aerogel layers wherein fibers from at least one fiber-reinforced aerogel layer are interlaced with fibers of an adjacent fiber-reinforced aerogel layer.

In one aspect, composite construction materials are described herein. In some embodiments, a composite construction panel comprises a substrate layer, a cover layer separated from the substrate layer by one or more spacers, and at least one mat disposed between the substrate layer and the cover layer, wherein the mat comprises at least one phase change material disposed in at least one phase change region.

A shear panel building material that includes a first facing membrane, a core matrix disposed on a face of the first facing membrane, and a semi-rigid or rigid material attached to the core matrix. The core matrix can include microspheres having a size of about 200 microns to about 800 microns, sodium silicate, and ethylene vinyl acetate. In one aspect, the shear panel is substantially free from glue and cement.

An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises a core with a top side and a bottom side. The top side has a plurality of spaced apart, upwardly oriented projections that define channels suitable for fluid flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly.

A structure includes a skin and a foam member. The foam member has a molded contour, the mold contour being configured to provide tooled surface for the skin. When the skin is a composite skin, the foam member provides support for the skin so that the skin can be cured under heat and pressure. A method of making the foam member for a foam stiffened structure includes creating a mold having an interior cavity which resembles a desired shape the foam member. A subsequent step involves introducing a foam mixture into the mold. Next, the foam mixture is allowed to polymerize so as to expand and distribute within the cavity of the mold. The method further includes selectively controlling a density of the foam member in the mold. The foam member is at least partially cured. The foam member is assembled with a skin to produce the foam stiffened structure.

The present invention relates to the use of an anisotropic fluoropolymer having a different intrinsic thermal conductivity in at least two directions as a heat conducting material in a thermally conductive article, to a thermally conductive article comprising said anisotropic fluoropolymer and to a process for the production of said anisotropic fluoropolymer.

Nanoporous three-dimensional networks of polyurethane particles, e.g., polyurethane aerogels, and methods of preparation are presented herein. Such nanoporous networks may include polyurethane particles made up of linked polyisocyanate and polyol monomers. In some cases, greater than about 95% of the linkages between the polyisocyanate monomers and the polyol monomers are urethane linkages. To prepare such networks, a mixture including polyisocyanate monomers (e.g., diisocyanates, triisocyanates), polyol monomers (diols, triols), and a solvent is provided. The polyisocyanate and polyol monomers may be aliphatic or aromatic. A polyurethane catalyst is added to the mixture causing formation of linkages between the polyisocyanate monomers and the polyol monomers. Phase separation of particles from the reaction medium can be controlled to enable formation of polyurethane networks with desirable nanomorphologies, specific surface area, and mechanical properties. Various properties of such networks of polyurethane particles (e.g., strength, stiffness, flexibility, thermal conductivity) may be tailored depending on which monomers are provided in the reaction.

A label for a bottle where the label is comprised of a laminate where an outer layer (3) is a material susceptible to losing opaqueness when made wet, and an inner layer (5) behind this first layer which is a material that is opaque, and such that it will maintain such opaqueness when wet.

The present invention relates to blowing agent compositions of carbon dioxide and at least one hydrochlorofluoroolefin (HCFO). The HCFOs can include, but are not limited to, 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd), 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) and mixtures thereof. The blowing agent compositions are useful in the production of low density insulating foams with improved k-factor made from thermoplastic resins. The blowing agent compositions may also optionally include one or more hydrofluoroolefins (HFOs).

Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material ad heating to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.
