Articles of composite construction and method of producing patterns thereon
First Claim
1. A composite article having at least one layer formed of reinforcing strands and a cured resin having a coloring component therein to produce an opaque resin of light color which coats said strands, said article having a surface layer comprised of surface veil impregnated with said cured resin and in which said reinforcing strands in said at least one layer underlying said surface layer are at least partially masked by said light color of said resin, said surface layer and said layer underlying said surface layer being of substantially the same said light color, said surface layer further including a color pattern which contrasts with said light color sublimated from a pattern carrier extending substantially into said surface veil impregnated with said cured resin.

Abstract
A process for producing sharp surface visible patterns on composite articles formed of resin coated reinforcing strands employs a liquid uncured resin having a coloring component therein to produce an opaque resin of light color to mask the color of the reinforcing strands. An absorbent surface veil is applied to the surface of the article before curing the resin to produce an absorbent opaque surface layer of light color into which a pattern of contrasting color is then transferred by sublimating an ink or dye pattern from a pattern carrier into the opaque resin impregnated surface layer and veil. Articles ready for application of the surface pattern thereto by sublimation may be produced using pultrusion or hand lay-up methods. Distribution of the surface pattern partially or entirely through the thickness of the surface layer results in an article having a surface in which the pattern remains sharply visible despite surface wear.
