Abstract
The present invention provides a composite molding tool including a surface coat that comprises metal powders and mineral fillers, and a composition comprising a resin mixture and metallic fillers. The composition includes at least about 45% metallic fillers, based on the weight percent of the total composition.
Claims13
A process of forming composite molding tools comprising the steps of:
- (a) applying at least one layer of a surface coat mixture to a model, producing a surface coat;
- (b) applying at least one layer of metal wool saturated in a resin coating mixture to said surface coat, producing a metal wool/resin mixture layer;
- and
- (c) applying a vacuum bag system to said metal wool/resin mixture layer, compressing said layer and drawing out excess resin mixture.

A process of forming composite molding tools comprising the steps of.
- (a) providing a model having a surface for forming said composite molding tools;
- (b) applying a surface coat mixture layer to said model, producing a surface coat;
- (c) applying a second surface coat mixture layer to said surface coat;
- (d) applying at least one layer of metal wool saturated in a resin coating mixture to said second layer of said surface coat, producing a metal wool/resin mixture layer;
- (e) applying a vacuum bag system to said metal wool/resin mixture layer;
- (f) compressing said metal wool/resin mixture layer and drawing out excess resin mixture;
- (g) placing said composite molding tool in an autoclave, applying pressure and further compressing said wool/resin mixture layer;
- (h) removing said vacuum bag system, exposing a back surface of said molding tool;
- (i) fitting a copper tubing system to said back surface;
- (j) applying at least one layer of a conductive aluminum slurry mixture to said copper tubing system;
- (k) constructing and attaching a chase to said back surface, wherein said chase includes eggcrates within the perimeter of said chase;
- and
- (l) filling said back surface and eggcrates with a resin mixture, resulting in one half of said composite molding tool;
- wherein a second half of said composite molding tool is constructed by repeating steps (a)-(l).
