Systems and methods are provided for simulating traction power and control in transportation systems under design conditions and/or utilizing real-time data.

In an example, a method for accelerated conditioning of a composite core sandwich coupon is described. The method includes setting a first temperature and a first relative humidity level of the conditioning apparatus, wherein a combination of the first temperature and the first relative humidity level correspond to a desired relative humidity level of the plurality of cells of the core layer at room temperature. The method includes maintaining the first temperature and the first relative humidity for a first period, wherein during the first period a core humidity of the plurality of cells in the core layer approaches the first relative humidity level. The method includes determining that the core humidity has reached the first relative humidity level. The method includes, based on determining that the core humidity has reached the first relative humidity level, adjusting the first temperature to a second temperature.

An impact resistant exterior sheathing gypsum building panel with an integrated impact resistant woven mesh which protects against impact from projectiles such as those conveyed by hurricane force winds is provided. Methods for manufacturing these exterior sheathing gypsum building panels with an integrated impact resistant woven mesh are also provided. An exterior sheathing system employing the exterior sheathing cementitious building panel is provided.

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.

A laminate includes: a base material; a circuit; an insulating layer provided between the base material and the circuit, the insulating layer including a thermally conductive filler; and an adhesive configured to bond at least the base material and the insulating layer. The base material and the insulating layer are bonded by the adhesive in part and in contact with each other in other parts. A plurality of spaces are formed in the insulating layer, and the adhesive fills at least a portion of the plurality of spaces.

An engine head gasket includes a base layer, an upper layer, and a lower layer. The base layer includes a base layer inner edge. The engine head gasket further includes an anti-preignition wrap defining a cylinder opening and wrapped around the base layer inner edge. The engine head gasket is configured with a combustion seal and selective thicknesses to direct a combustion sealing load to a cylinder block. The anti-preignition wrap shields angular corners of the base layer inner edge from a cylinder to limit preignition.

A marine deck member and the process for forming the same are provided. The marine deck member comprises a sandwich-type composite panel made by a compression molding process. In such a process, the panel is made by subjecting a heated stack of layers of material to cold pressing in a mold. The cellular core has a 2-D array of cells, with end faces open to the respective layers or skins. The surface traction of this type of composite panel can be enhanced for marine deck applications by controlled debossing, or embossing, of the first skin while it cools in the compression mold. The debossing effect can be affected by applying pressurized gas, e.g., pressurized air, onto the outer surface of the first skin while in the compression mold. The embossing can be affected by applying vacuum pressure on the outer surface of the first skin while in the compression mold.

A composite molded cargo body panel including a core, an interior skin secured to a first side of the core having a thickness, and exterior skin secured to a second side of the core, and a plurality of recesses. The plurality of recesses are dispersed along a first direction at intervals in the interior skin, with the core thickness at each of the plurality of recesses being reduced compared to a maximum core thickness, and each of the plurality of recesses defines a support surface. A pocket is formed in each of the plurality of recesses, with the core thickness at the pocket being less than the core thickness at each of the plurality of recesses. A plurality of logistics inserts are attached to the respective support surfaces of the plurality of recesses so that, at each of the plurality of recesses, the logistics insert extends across the pocket.

A film comprising a perforated layer, wherein the perforated layer is characterized by water vapor transmission rate (WVTR) of at least 300 gr/m2/day; and wherein the perforated layer is characterized by a liquid permeability of less than 0.6 gr when measured according to AATCC 35. Further, methods of manufacturing the composition of the invention are provided.

Provided is a conductive laminate including a base material and a conductive ink film provided on the base material, in which a region that extends from a position being away from a first main surface toward a second main surface by a distance equivalent to 50% of a thickness of the conductive ink film to the second main surface has a first void ratio of 15% to 50%, and a second void ratio in a region that extends from the first main surface toward the second main surface to a position being away from the first main surface by a distance equivalent to 10% of the thickness of the conductive ink film has a second void ratio which is smaller than the first void ratio.
