Abstract: The present teachings relate generally to a one part room temperature curable composition. e.g., a one-part epoxy-based adhesive precursor composition. The composition may include an epoxy resin, and a filler. The composition may include a flame retardant sufficient so that when the adhesive precursor composition is cored, it meets applicable requirements for flame retardancy of 14 C.F.R. § 25.853 for aircraft inferior cabins. An amount of a curing agent may be included. The selection of the epoxy resin, curing agent, or both, may afford curing with or without the need for an application of heat. The epoxy resin, the filler, any flame retardant and the curing agent are admixed to define a substantially homogenous admixture, thereby defining a mass of adhesive precursor.

Abstract: A method comprising providing a polymeric substrate having a melting point of from about 130° C. to about 190° C., and locating a material layer onto the substrate, wherein the material layer comprises one or more polymeric materials that liquefy upon exposure to temperatures of at least about 100° C., to blend with a softened portion of the polymeric substrate. Upon exposure of one or more of the substrate and the material layer to a stimulus, the temperature is increased in a predetermined temperature zone of one or more of the substrate and material layer to cause blending of the one or more polymeric materials of the material layer with the softened portion of the polymeric substrate.

Abstract: A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (is) at least one consolidated fibrous insert having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier will be a mass of activatable material.

Abstract: An article comprising: (a) a carrier having a predetermined shape to guide one or more expansion directions of an injection molded expandable material; (b) the injection molded expandable material on the carrier; wherein the expandable material is formed on the carrier at one or more angles perpendicular to the one or more expansion directions; and wherein the expandable material is capable of being activated to expand under an activation condition to come into contact with, and adhere to one or more walls defining a cavity in order to at least partially fill the cavity.

Abstract: Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material and heating to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.
