摘要:
This invention relates to a composite board including: a core having upper and lower surfaces and at least one aperture extending therebetween, at cast one upper reinforcing layer disposed on the upper surface of the core and at least one lower reinforcing layer disposed on the lower surface of the core, at least one tie member passing through the substantially aligned apertures, each said tie member having a first end portion protruding through said aligned apertures from said upper reinforcing layer and a second end portion protruding through aligned apertures from a lower reinforcing layer, with the surface covered by artificial turf as a means of alternative gripping for the rider. The artificial turf is secured to the upper layer of the skateboard by an adhesive. A process for preparing the composite board and skateboard deck formed from the composite board and artificial turf surface are disclosed.

A wind turbine composite structure for absorbing radio frequency energy, the wind turbine composite structure comprising: a sandwich panel construction comprising a core having an inner surface and an outer surface, disposed between an inner skin and an outer skin; the outer surface and the outer skin facing towards an exterior surface of the wind turbine composite structure and the inner surface and the inner skin facing towards an interior of the wind turbine composite structure; a reflector layer disposed adjacent to the inner skin; and a functional layer comprising printed or deposited circuitry, the functional layer forming a radar absorbing circuit in combination with the reflector layer, wherein the functional layer is printed or deposited directly on to the outer surface of the core.
摘要:
A waterproof roofing laminate comprises a cellular plastic support layer, an insulation layer located thereon, and a cover layer that reflects radiant energy such as infrared light, visible sunlight, and ultraviolet light. The cellular support layer contains a plurality of cavities therein that can be open or closed cell. The support layer can also have a solid continuous top and/or bottom surface layer. The insulation layer is located on the support layer and can be formed of numerous materials including natural or synthetic fibers, organic or inorganic material, and is free of cement and styrofoam. The waterproof cover layer is located on the insulation layer and is capable of reflecting radiant energy by being of a light color and/or containing radiant reflective materials therein.

A body structure for a door and/or furniture is provided. The body structure comprises a first artificial stone skin backed with a first fiber layer, a second artificial stone skin backed with a second fiber layer, and a central composite core comprising porous ceramic blocks and porous ceramic pieces and structural foam or an artificial stone mix. A reinforcing grid is placed between the first artificial stone skin and the second artificial stone skin. The body structure for a door and/or furniture is manufactured by manufacturing artificial stone skins, manufacturing a central composite core comprising porous ceramic blocks and porous ceramic pieces between two of the artificial stone skins, and introducing a liquid mix of structural foam or an artificial stone mix between the artificial stone skins, whereby the structural foam or the artificial stone mix fills gaps between the porous ceramic blocks, sets to create the central composite core.
摘要:
A cargo trailer includes a floor, a roof and a side wall extending vertically upward between the floor and roof. The side wall includes a substantially gas impermneable outer liner panel and a substantially gas impermeable inner liner panel. The inner liner panel includes at least one glass and polymer layer and one gas impermeable barrier layer. The inner liner panel can also be used to form the roof and replace the outer liner panel.
摘要:
The present invention is a method and material for using a sorbent material to capture and stabilize mercury. The method for using sorbent material to capture and stabilize mercury contains the following steps. First, the sorbent material is provided. The sorbent material, in one embodiment, is nano-particles. In a preferred embodiment, the nano-particles are unstabilized nano-Se. Next, the sorbent material is exposed to mercury in an environment. As a result, the sorbent material captures and stabilizes mercury from the environment. In the preferred embodiment, the environment is an indoor space in which a fluorescent has broken.

A fragrance emitting patch including a primary porous layer having a top and a bottom surface, a secondary layer having a top and a bottom surface, a construction adhesive arranged between the primary layer and the secondary layer for securing the primary and secondary layers to one another, the primary layer being provided with a fragrance, and an absolute difference of a Hildebrand solubility parameter of the construction adhesive and the Hildebrand solubility parameter of the fragrance is greater than 1.5.
摘要:
A material comprising aerogel particles and a polytetrafluoroethylene (PTFE) binder is formed having a thermal conductivity of less than or equal to 25 mW/m K at atmospheric conditions. The material is moldable or formable, having little or no shedding of filler particles, and may be formed into structures such as tapes or composites, for example, by bonding the material between two outer layers. Advantageously, composites may be flexed, stretched, or bent without significant dusting or loss of insulating properties.

摘要:
A flexible face-slab has a layer (11) of natural sandstone from which its natural binding material has at least been partially removed, but without disturbing its natural granular structure consisting of sand-grains being in contact with each other. The empty spaces, created in the layer (11) after the removal of the natural binding material are partially or completely filled with a flexible binding agent, which can be a synthetic resin-based binder. One side of the layer (11) of natural sandstone is strengthened by a base layer (12) that acts as a stabilizing layer. This may incorporate a mesh (13), woven cloth material, or threads of natural or an artificial material. The total thickness (17) of the sandstone layer (11) and the base layer (12) after completion of the manufacturing process may range between 2 and 6 mm.
摘要:
A new foam coated nonwoven fibrous mat having properties particularly suited for a facer on gypsum wallboard, laminates made therefrom and the method of making the mat is disclosed. The mat preferably contains a major portion of glass fibers and a minor portion of a resinous binder. The foam coating is permeable and reduces fiber dust and abrasion experienced in the past with relatively coarse, relatively inexpensive glass fibers in the mat. Contrary to previous methods, the foam coated fibrous mat is made in-line on a wet mat forming production line by applying a wet foam binder onto a wet, fibrous web followed by drying and curing in-line.
