    Abstract: This invention provides curable fluoroelastomer compositions comprising: (a) a fluorine-containing polymer or blend of fluorine-containing polymers each comprising interpolymerized units derived from one or more fluorine-containing ethylenically unsaturated monomers; (b) at least one organo-onium compound such as those selected from the group consisting of ammonium, arsonium, phosphonium, stibonium, amino-phosphonium, phosphorane (e.g. triarylphosphorane), iminium, and sulfonium compounds; and (c) one or more aryl, allyl or alkyl carbonate-blocked compound as a crosslinking agents. Methods of curing fluoroelastomer compositions, and articles made therefrom are also described.

    Abstract: Fiber reinforced resin matrix composite laminates are provided comprising: at least one layer of fiber reinforced resin matrix comprising a cured resin matrix; and a surfacing construction bound to the cured resin matrix and forming a surface of the laminate, comprising: at least one barrier layer; and at least one cured adhesive layer derived from high temperature cure adhesive. In some embodiments, barrier layer(s) may be substantially impermeable to organic solvents, water, and/or gasses. In another aspect, fiber reinforced resin matrix composite laminates are provided comprising: a) at least one layer of fiber reinforced resin matrix comprising a cured resin matrix; and b) a surfacing construction bound to the cured resin matrix and forming a surface of the laminate, comprising: at least one barrier layer; and at least one electrically conductive layer. In another aspect, a surfacing construction is provided comprising a barrier layer and a curable adhesive layer.
