An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises plurality of panels, each panel comprising a core with a top side and a bottom side. The top side has a plurality of top projections. The top projections form top side water drainage channels. The panels have edges, with the edges of one panel abutting the edges of adjacent panels, thereby forming a drainage path between adjacent panels. The panel edges have vertical support extensions that extend into the drainage paths between adjacent panels. The vertical support extensions have an upper surface for supporting an artificial turf assembly overlying the turf underlayment layer, and the panel edges having one or more complementary indentations corresponding to vertical support extensions of adjacent panels. When the panels move toward each other, thereby closing drainage paths between adjacent panels, the vertical support extensions are received in the corresponding indentations.

Disclosed is a tile unit (10) that includes a resin net (20), a plurality of tiles (30) disposed on a front side of the resin net, and a magnet sheet (40) disposed on a back side of the resin net, with the tiles being bonded and fixed to the magnet sheet with the resin net interposed therebetween.

The purpose of the present invention is to provide an inorganic fiber laminate having improved uniformity of surface density, as well as provide a vacuum insulation material using the same, and a manufacturing method for the same. The present invention relates to an inorganic fiber laminate (10) at least including a first inorganic fiber mat (1) that has a high-surface-density section (1a) and a low-surface-density section (1b), and a second inorganic fiber mat (2) that has a high-surface-density section (2a) and a low-surface-density section (2a), wherein the high-surface-density section (1a, 2a) of the first inorganic fiber mat (1) and/or the second inorganic fiber mat (2) are/is laminated on the low-surface-density section (1b) of the first inorganic fiber mat (1), and the high-surface-density section (1a, 2a) of the first inorganic fiber mat (1) and/or the second inorganic fiber mat are/is laminated on the low-surface-density section (2b) of the second inorganic fiber mat (2).

The invention herein pertains to pavement marking patterns and the application thereof to roads, streets, walkways and the like. Various pattern designs for the markings are available to replicate layers of bricks, cobblestones, horizontal signage, logos and other components. The marking patterns are composed of two or more independent sections. The first section is a grid representing for example, the mortar joints in a brick wall. The second sections or inserts, for example represent bricks which are contained within the grid. As the first and second sections are generally formed from different colored, preferably thermoplastic materials, a hot melt adhesive spray is utilized on the bottom surface of the marking pattern to bridge the intersections between the first and second sections to maintain the integrity of the marking pattern for convenience during handling and application to a substrate.

A composite material includes a plurality of reinforcements arranged in a plurality of layers. Each reinforcement comprises a tapered shape that allows the reinforcements of a particular layer to nest with reinforcements of an adjacent layer. The composite material further includes an adhesive that is at least partially between the layers of reinforcements.

The present invention provides a panel assembly comprising a plurality of panels arranged in edge-to-edge format having joints between each pair of adjacent panels in the assembly. A copper-containing material, such as copper tape with adhesive backing, is provided in or near the joints in the assembly to render the joints less susceptible to bacterial contamination.

This invention relates to tufted floorcovering articles that are washable in commercial, industrial, and/or residential washing machines. In particular, this invention relates to modular carpet tiles that are constructed in such a way as to withstand exposure to at least one wash cycle in an automatic washing machine. The carpet tiles are designed to be soiled, washed, and re-used, thereby providing ideal end-use applications such as entryway floorcovering articles. A further advantage includes the ability to print advertising logos on the carpet tiles and easily change out the advertising logos as desired. Both features of the carpet tile of the present invention are achievable, at least in part, because the surface of the tile that contacts the floor does not require any type of adhesive in order to use the carpet tile for its intended function.

Various embodiments are directed to an airline carpet kit comprising a plurality of carpet components collectively forming a substantially continuous floor covering, for example, for use within an aircraft interior. Each of the plurality of carpet components comprises a tufted carpet backing having a plurality of carpet tufts extending from a back surface of the carpet backing and above a top surface of the carpet backing; and an edge strip comprising an amorphous plastic material, wherein the edge strip extends around a lateral edge of the carpet backing between a base portion embedded within a back surface of the carpet backing and an edge surface defining a perimeter edge of the carpet component. The edge surface of a first carpet component abuts an edge surface of an adjacent second carpet component to form an at least substantially continuous floor covering for an aircraft interior.

An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises plurality of panels, each panel comprising a core with a top side and a bottom side. The top side has a plurality of top projections. The top projections form top side water drainage channels. The panels have edges, with the edges of one panel abutting the edges of adjacent panels, thereby forming a drainage path between adjacent panels. The panel edges have vertical support extensions that extend into the drainage paths between adjacent panels. The vertical support extensions have an upper surface for supporting an artificial turf assembly overlying the turf underlayment layer, and the panel edges having one or more complementary indentations corresponding to vertical support extensions of adjacent panels. When the panels move toward each other, thereby closing drainage paths between adjacent panels, the vertical support extensions are received in the corresponding indentations.

In a composite material structure, which is configured as a fiber-reinforced plastic composite material extending in one direction and having a plurality of holes defined at intervals in a row in the one direction and which is subjected to a tensile load and/or a compressive load in the one direction, a peripheral region around the holes comprises a first area obtained by bending composite material, which is reinforced using continuous fibers that have been made even in a longitudinal direction, so that a center line of a width of the composite material weaves between adjacent holes and zigzags in the one direction. A tensile rigidity and/or a compressive rigidity in the one direction of the peripheral region around the holes is lower than a tensile rigidity and/or a compressive rigidity in the one direction of other regions that surround the peripheral region.
