Abstract (en)

[origin: WO9107281A1] A method of providing a finish to an article (10) containing resin wherein an overlay (12) of sheet material that is impregnated with thermosetting resin -- typically a fabric of a type including metallic, synthetic fiber, natural fiber and ceramic cloths impregnated with epoxy resin -- is wrapped about or laid on an underlay (11) of material that is also impregnated with thermosetting resin -- typically a resin material reinforced with fibers of the graphite, glass, aramid, or ceramic types. The overlay (12) and underlay (11) are cured under heat and pressure in an oven at the same time, causing cohesive bonding of the resin within each. The resin exudes through the fabric overlay (12) during curing and forms a hard transparent shell of cured resin to the composite article. The embedded sheet material selectively imparts color, pattern, texture, reflectivity, penetration resistance, tensile strength, thermal and electrical conductivity, and other visual and mechanical properties to the composite article as desired.
