Jeffrey Allan Pfaendtner - Blue Ash OH
Michael James Weimer - Loveland OH
William Evan McCormack - West Chester OH
Joseph David Rigney - Milford OH
Mark Lloyd Miller - Schenectady NY
John Lewis Lackman - Cincinnati OH

Assignee:

General Electric Company - Schenectady NY

International Classification:

B05D 302

US Classification:

427142, 427287, 4273761, 4273766, 427404, 427405, 427377, 427350, 4274301, 427421, 427429

Abstract:

A method for coating an article includes preparing a coating precursor paint including aluminum-containing pigment particles, a temporary organic binder comprising an acrylic, and a solvent for the temporary organic binder. The coating precursor paint is applied to a surface of the article and thereafter heated to a temperature of from about 1200Â F. to about 2100Â F. in a non-oxidizing environment.

International Classification:

B32B 27/04
B05D 3/00

US Classification:

4284735, 427296

Abstract:

Method includes forming a preform utilizing a polyimide resin-impregnated fiber-reinforced layers; removing solvent from the system at initial vacuum, pressure, and temperature conditions for an initial time interval sufficient to remove substantially all the solvent; imidizing the polyimide resin system under second vacuum, pressure, and temperature conditions for a second time interval sufficient to substantially completely imidize the polyimide resin; consolidating the preform following imidization under third vacuum, pressure, and temperature conditions and including applying pressure to the preform when the preform is at a predetermined temperature; and solidifying the preform under fourth vacuum, pressure, and temperature conditions to provide a cured laminate structure having a shape of a turbine engine component. A method is provided for designing the polyimide resin overall cure cycle dependent on the desired outcome at the solvent removal stage, the imidization stage, the consolidation stage, and the solidification stage.
