    Abstract: A unitary expanded metal mesh is provided having a down-roll direction, the mesh comprising: a) linear strands that are substantially parallel to the down-roll direction; and b) cross strands which meet the linear strands at nodes. Composites including the unitary expanded metal mesh of the present disclosure and a polymeric matrix are also provided. The unitary expanded metal mesh and composites may be provided as roll goods having, in some embodiments, uninterrupted linear down-roll metal strands for unlimited length. Methods of making the unitary expanded metal mesh of the present disclosure are provided.

    Abstract: Provided is a protection film including a plurality of layers, including a first carrier layer having a plurality of electrically conductive fibers; a metal layer; and a second carrier layer having a plurality of electrically conductive fibers. Each of the first and second carrier layers has a void volume at least partially filled with a hardenable composition. Also provided is a protection film including a first metal layer, a carrier layer, and a second metal layer, in which the carrier layer is at least partially filled with a hardenable composition. These films can provide lightning strike protection with suitable tensile, rigidity and tack properties for automatic tape layup and automatic fiber placement applications.

    Abstract: Curable sealant compositions comprise the components: a) x weight percent of at least one polythiol; b) y weight percent of at least one unsaturated compound having at least two non-aromatic carbon-carbon double bonds, at least one carbon-carbon triple bond, or a combination thereof; c) from 0.01 to 8 weight percent of at least one organoborane-amine complex; d) from 0.05 to 10 weight percent of at least one organic peroxide; and e) from 0.01 to 10 weight percent of a photoinitiator system capable of generating free radicals upon exposure to actinic radiation. Each of x and y represents a positive real number. The sum x+y is in the range of 72 to 99. The weight percent ranges of the components a)-e) are based on the total weight of the components a)-e). A seal cap including the curable sealant composition and methods of making and using the curable sealant compositions are also disclosed.

    Abstract: A composition is provided comprising: a) a curable epoxy resin; and b) 0.01-30% by weight of a polycarbodiimide according to Formula I: R—{—N═C═N—R—}n—N═C═N—R  (I) wherein n is an integer between 0 and 100, and wherein each R is independently selected from aromatic and aliphatic groups which contain between 1 and 24 carbons and which are optionally substituted, typically comprising 0.1-20% by weight of the polycarbodiimide. In some embodiments the present disclosure provides sheet materials made of such cured, uncured or partially cured materials. In some embodiments these compositions may be useful in making surfacing films for composite parts and may demonstrate good paint stripper resistance and microcrack resistance.

    Abstract: Provided is an electrically-conductive assembly and methods thereof. The electrically-conductive assembly includes a release liner having a major surface, a conductive layer extending across a portion of the major surface according to a pre-determined shape, a pressure-sensitive adhesive layer disposed between the release liner and the conductive layer. The pressure-sensitive adhesive layer can be mutually coextensive with the conductive layer. An insulating layer is disposed on the conductive layer and the release liner, such that the conductive layer and the pressure-sensitive adhesive layer are captured between the insulating layer and the major surface of the release liner. The provided assembly can sustain an electrical current to carry signals or distribute power in layered composite structures.
