Disclosed herein is an insulated panel for facilitating post-tensioning of the insulated panel, in accordance with some embodiments. Accordingly, the insulated panel may include a frame, a first layer, a second layer, a second layer, a third layer, a fourth layer, and a fifth layer. Further, the frame may include a frame-end arranged in an arrangement forming an interior space. Further, the first layer of a building material is disposed in the interior space. Further, the second layer of an insulating material is disposed on the first layer. Further, the third layer of a cable is disposed on the second layer. Further, the fourth layer of the insulating material is disposed on the third layer. Further, the fifth layer of the building material is disposed on the fourth layer. Further, at least one of the first layer and the fifth layer may be cured for producing the insulated panel.

A ball includes a bladder that has a majority weight component of a material of a first material class. The ball includes at least one intermediate layer that is arranged exterior to the bladder and that has a majority weight component of the material of the first material class. The ball includes at least one exterior layer that is arranged exterior to the at least one intermediate layer and that has a majority weight component of the material of the first material class.

Provided herein are multilayer damping laminates comprising at least one constraining layer and at least one discontinuous damping layer. At least one discontinuous damping layer comprises one or more damping material regions and one or more gap regions, wherein the percent coverage of at least one discontinuous damping layer by one or more damping material regions is less than 99%. Also provided are systems and methods using the multilayer damping laminates.

The present invention relates to a reinforcing structure, such as a reinforcing structure for reinforcing a wind turbine blade, comprising: a first composite element layer comprising at least two carbon fibre reinforced composite elements; a second composite element layer comprising one or more carbon fibre reinforced composite elements; an interlayer sandwiched at least partly between the first and the second composite element layer, the interlayer comprising an electrically conductive portion and a non-conductive portion surrounding the conductive portion, the conductive portion abutting exactly two of the carbon fibre reinforced composite elements comprised in the first composite element layer. A method for manufacturing such a structure is also provided.

The invention relates to a hollow board material comprising a first sheet and a second sheet. A first and a second lath are arranged in parallel between the first sheet and the second sheet along opposite edges of the hollow board material. The first lath and the first sheet are attached to each other by means of a first metal gripping lamina which at least partly covers the first lath. The second lath and the first sheet are attached to each other by means of a second metal gripping lamina which at least partly covers the first lath. Optionally, the first lath and the second sheet are attached to each other by means of a third metal gripping lamina and optionally the second lath and the second sheet are attached to each other by means of a fourth metal gripping lamina. The metal gripping laminas have a first face and a second face which are opposed to each other. Each face comprises a plurality of sharp projections extending substantially perpendicular therefrom and into the laths or the sheets respectively. The metal gripping laminas thereby provides a hollow board material and increases the bending strength of the hollow board material. The invention further relates to a furniture comprising said hollow board material and method for producing said hollow board material.

Improved containment mats and systems of containment mats may include multiple adjoining mats with a top surface and a bottom surface. The multiple mats may provide a modular structural mat system that may be installed at a drill site, with multiple mats placed adjacent to each other with a lap joint connecting adjacent mats. A geotextile may be used to cover the lap joints and a coating applied to the geotextile. Such a system may provide containment of potential spills, a reliable working surface for drilling operations, and relatively fast and less expensive installation.
