Flaky alumina particles including mullite in a surface layer of the flaky alumina particles. A method for producing flaky alumina particles including forming a mixture by mixing together an aluminum compound that contains elemental aluminum, a molybdenum compound that contains elemental molybdenum, and silicon or a silicon compound that contains elemental silicon, the aluminum compound being in an amount greater than or equal to 50 mass %, calculated as Al.sub.2O.sub.3, the molybdenum compound being in an amount less than or equal to 40 mass %, calculated as MoO.sub.3, the silicon or the silicon compound being in an amount of 0.5 mass % or greater and less than 10 mass %, calculated as SiO.sub.2, relative to a total mass of the flaky alumina particles taken as 100 mass %; and firing the mixture.

The laminate of the present disclosure includes multiple glass ceramic layers each containing quartz and a glass that contains SiO.sub.2, B.sub.2O.sub.3, Al.sub.2O.sub.3, and M.sub.2O, where M is an alkali metal. The B concentration of a surface layer portion of the laminate is lower than the B concentration of an inner layer portion of the laminate.

A composite substrate that is composed of a resin layer including an interlayer connection metal conductor and multiple ceramic layers that each include interlayer connection metal conductor, such that the resin layer is interposed between the ceramic layers, and the interlayer connection metal conductor in the resin layer is integrated with the interlayer connection metal conductors in the ceramic layers.

The present invention relates to a flexible ballistic armor apparatus for deflecting high velocity firearm, fragmentation, or shrapnel projectiles with a flexible armor unit. The apparatus minimizes the deterioration of the armor when subjected to shock waves or shear forces of a ballistic impact. The present invention also relates to the use of a flexible armor unit with soft body armor, a vehicle, a vessel, an aircraft or in structural applications.

A process for manufacturing floor tiles comprising the following steps: scattering granules (62) of a thermoplastic material on a conveying member (52) in order to obtain a first layer of granules (64), superimposing several sheets (5B, 5C) in order to obtain a plurality of adjacent sheets on the first layer of granules (64), each of the sheets containing at least 50 wt % of glass fibers, scattering granules (70) of a thermoplastic material on the uppermost sheet (5B) in order to obtain a second layer of granules (72), pressing and heating the first layer of granules, the plurality of adjacent sheets and the second layer of granules, melting or at least softening the first layer of granules and the second layer of granules, the plurality of sheets being at least partly impregnated by the thermoplastic material of the first layer of granules and of the second layer of granules in order to obtain a core layer after cooling, and using the core layer to produce at least a slab, and using the slab to obtain the floor tiles.

Environmentally responsible insulating construction blocks and structures constructed primarily of recycled materials are disclosed. The environmentally friendly construction blocks and structures comprise shredded rubber tire pieces coated with silica fume, slag cement and cement, which are then mixed with water and formed in a mold. A layer of grout or a fireproof material may be disposed on one side of the environmentally responsible insulating construction block. The environmentally responsible insulating construction blocks provide high insulation as well as strength for applications such as green roofing, wall construction and green roofing decks. Environmentally friendly structures can be built by pouring the coated shredded rubber tire pieces into molds to form walls, and then to pour a layer of the coated shredded rubber tire pieces as a roof deck, thereby creating a self-supporting structure in a monolithic pour.

This infrared light shielding laminate includes: an ITO particle-containing layer; and an overcoat layer which covers an upper surface of the ITO particle-containing layer, wherein core shell particles are present in a state of being in contact with each other in the ITO particle-containing layer, and the core shell particle includes an ITO particle serving as a core and an insulating material serving as a shell that covers the core.

A method is described for reducing the afterflame of a flammable, meltable material. A textile composite is described comprising an outer textile comprising a flammable, meltable material, and a heat reactive material comprising a polymer resin-expandable graphite mixture.

A panel having side edges for connection to a further panel in order to cover a surface of a room, includes an upper side, an underside, and at least four side edges. The panel has a multilayer structure including an elastic base layer, made entirely or predominantly of an elastically adjusted polyurethane, and above the base layer a top layer which compared to the base layer is less elastic. The top layer is pressed via an adhesive layer with the base layer to form the multi-layer structure.
