The present disclosure generally relates to systems and methods for composites, including short-fiber films and other composites. In certain aspects, composites comprising a plurality of aligned fibers are provided. The fibers may be substantially aligned, and may be present at relatively high densities within the composite. For example, the composite may include substantially aligned carbon fibers embedded within a thermoplastic substrate. The composites may be prepared, in some aspects, by dispersing fibers by neutralizing the electrostatic interactions between the fibers, for example using aqueous liquids containing the fibers that are able to neutralize the electrostatic interactions that typically occur between the fibers. The liquids may be applied to a substrate, and the fibers may be aligned using techniques such as shear flow and/or magnetism. Other aspects are generally directed to methods of using such composites, kits including such composites, or the like.

A laminated core includes a plurality of electrical steel sheets which are stacked on each other and of each of which both surfaces are coated with an insulation coating; and an adhesion part which is provided between the electrical steel sheets adjacent in the stacking direction and adheres the electrical steel sheets to each other, wherein an adhesive for forming the adhesion part includes a first phase and a second phase, wherein the adhesion part has a sea-island structure of the first phase which is a sea structure portion and the second phase which is an island structure portion, wherein the first phase contains an epoxy resin, an acrylic resin, and a curing agent, wherein the first phase has an SP value of 8.5 to 10.7 (cal/cm.sup.3).sup.1/2, wherein the second phase contains an elastomer, and wherein the second phase has an SP value of 7.5 to 8.4 (cal/cm.sup.3).sup.1/2.

A method for manufacturing a vapor deposition mask including a resin layer, and a magnetic metal layer formed on the resin layer, the method including the steps of: providing a substrate; forming a resin layer by applying a solution including a resin material or a precursor solution of a resin material on a surface of the substrate, and then performing a heat treatment thereon; forming a magnetic metal layer on the resin layer, mask portion including a solid portion where a metal film is present and a hollow portion where the metal film is absent; forming a plurality of openings in a region of the resin layer that is located in the hollow portion of the mask portion; and removing the resin layer from the substrate after forming a plurality of openings in a region of the resin layer.

This invention relates to a washable multi-component magnetic floor mat with a hidden base component. The floor mat contains a textile component and a base component. The textile component and the base component are attached to one another by magnetic attraction. The magnetic attraction is provided by incorporation of magnetic particles in both the textile and base components. The textile component is designed to be soiled, washed, and re-used, thereby providing ideal end-use applications in areas such as building entryways. The present invention eliminates the need to wash the base component of the floor mat which results in environmental, cost and labor conservation. Alignment and deployment of the textile component with the base component in an efficient manner is also described herein.

A noise suppression sheet comprises a pair of metal magnetic layers and a non-magnetic metal layer interposed between the pair of metal magnetic layers, and can achieve high magnetic shield characteristics on both surfaces.

A method of processing sheet stock in the creation of plastic cards, such as gift cards or credit cards that include special effects and/or security measures. A card formed by such methods is also disclosed. The method provides for two or more dissimilar materials to be bonded together while maintaining the integrity of the card and as any graphics, security features, and/or special effects provided thereon. Thermoset and thermobond adhesive layers are placed between a first material layer and a second material layer of the sheet stock. The thermoset and thermobond adhesive layers allow the first and second material layers to move independently and to expand and contract at different rates relative to each other. The adhesive layers enable the sheet stock to be rolled up for shipping or storage and further enable the end product produced therefrom to have a planar profile.

An embodiment of the present invention provides an electrical steel sheet laminate, including: a plurality of electrical steel sheets; and a fusion layer disposed between the electrical steel sheets, wherein the fusion layer includes an olefin-based semi-crystalline polymer and at least one inorganic metal compound of a metal phosphate and a metal chromate.

An actuator is described, including a first sheet comprising a plurality of first openings,; and a second sheet comprising a plurality of second openings; wherein the first and second sheets are stacked together such that at least one of the first and second openings are misaligned; and the actuator is configured to move from a first state to a second state, wherein in the first state, out-of-plane motion of the first and second sheets is permitted; and in the second state, the first and second sheets as well as the misaligned first and second openings are jammed together to restrict the out-of-plane motion of the first and second sheets. Methods of actuating and making such actuator are also described.

In a magnetic shield material comprising a magnetic layer containing a magnetic material and an electrically conductive layer containing an electrically conductive material, the electrically conductive layer is designed to have a thickness corresponding to a frequency band of electromagnetic wave to be shielded. More specifically, the thickness of the electrically conductive layer (thickness of the aluminum foil in the drawing) is designed to have a thickness to maximize magnetic field shield effect of the magnetic shield material (thickness of the aluminum foil corresponding to peak value frequency in curve E in the drawing) in a frequency band of electromagnetic wave to be shielded. This makes it possible to obtain good magnetic field shield effect of the magnetic shield material in the frequency band of electromagnetic wave to be shielded.

A method is provided for the production of a wound nanocrystalline magnetic core in which a nanocrystalline metal strip made of (Fe.sub.1-aM.sub.a).sub.100-x-y-z-α-βCu.sub.xSi.sub.yB.sub.zM′.sub.αX.sub.β is pre-wound to form a first coil. An insulating foil is provided that is coated with an adhesive on at least one side. An adhesive is applied to the nanocrystalline metal strip to laminate the insulating foil onto the metal strip and thereby to stabilise the metal strip as it is wound off the coil. The laminated nanocrystalline metal strip and the insulating foil are bifilar wound to form a bifilar, layer-insulated coil.
