    Abstract: A low-density, halogen-free epoxy composition that is flame-resistant upon curing and is suitable for use as a potting compound. The epoxy composition includes: (a) an epoxy component; (b) at least one curative; (c) at least one latent curing accelerator; (d) a toughening component that includes nano-sized core shell rubber (CSR) particles having particle size of less than 1 micron; (e) a fire-retardant component that is halogen-free; and (f) hollow microspheres for reducing the density of the composition. The fire-retardant component includes a mixture of: (i) at least one polyphosphate; (ii) at least one metal borate; and (iii) at least one compound selected from alkaline earth metal hydroxides and aluminum hydroxides.

    Abstract: A surfacing material that can provide improved UV resistance while providing good surface properties. The surfacing material includes a resin layer formed from a curable resin composition containing: (A) one or more cycloaliphatic epoxy resin(s), each having two or more epoxy groups per molecule; (B) an epoxy-amine adduct having two or more epoxy groups per molecule and obtained by a reaction of (i) an epoxy compound having two or more alicyclic epoxy groups per molecule with (ii) an amine compound having two or more amino groups per molecule; (C) a curing agent and/or a catalyst; (D) ceramic microspheres; and (E) a flow control agent in the form of inorganic particles, which are not ceramic microspheres.

    Abstract: A method for surface preparation of a composite substrate prior to adhesive bonding. The surface preparation method includes applying a resin-containing peel ply onto a composite substrate, followed by co-curing. The resin-containing peel ply contains a non-removable textile carrier and a removable woven fabric embedded therein. After co-curing, the peel ply is removed from the composite substrate such that the removable woven fabric is removed but the non-removable textile carrier and a film of residual resin remain on the composite substrate, thereby creating a modified, bondable surface on the composite substrate. The composite substrate with the modified surface can be bonded to another composite substrate, whereby the textile carrier remains an integrated part of the final bonded structure.

    Abstract: A surfacing material that is capable of ultraviolet (UV) protection and self-releasing from a mold surface. The surfacing material is a multilayer structure composed of a curable resin layer laminated to a self-releasing layer. The surfacing material is designed to be co-cured with a composite substrate, for example, a prepreg layup. After co-curing, the composite part surfaced with the surfacing material is releasable from the mold surface with ease. The self-releasing layer functions as a UV blocking layer until the cured composite substrate is ready for painting. When the self-releasing layer removed, a paint-ready surface is revealed. Such surface does not require any surface preparation prior to painting.

    Abstract: A method for bonding composite substrates is disclosed. A curable surface treatment layer is applied onto a curable composite substrate, followed by co-curing. After co-curing, the composite substrate is fully cured but the surface treatment layer remains partially cured. The surface treatment layer may be a resin film or a peel ply composed of resin-impregnated fabric. If a peel ply is used, the peel ply is peeled off after co-curing, leaving behind a remaining thin film of partially cured resin. A subsequent dry physical surface treatment, such as plasma, is carried out to physically modify the surface of the surface treatment layer. After dry physical surface treatment, the composite substrate is provided with a chemically-active, bondable surface, which is adhesively bonded to another composite substrate to form a covalently-bonded structure.
