Abstract

A method for repairing window laminates in which two plies have become separated to create a void, and wherein moisture may have entered through an edge of the window laminate and into the void. The method includes the steps of: placing the window laminate in a vacuum bag and inserting the vacuum bag containing the window laminate into an oven or autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove the moisture between the plies; removing the vacuum bag and window laminate from the oven, and removing the window from the vacuum bag; forcing a needle on a syringe through the edge of the window laminate in the area of the void; and injecting an adhesive in the syringe into the void to fill the void with the adhesive.

Claims (32)

1 . A method for repairing a window laminate which has been delaminated and wherein moisture has entered into a void created by delamination, comprising the steps of:

placing the window laminate into a vacuum bag, sealing the vacuum bag closed and placing the vacuum bag containing the window laminate into an oven or an autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove moisture between plies of the window laminate;

removing the vacuum bag and the window laminate from the oven or the autoclave; and removing the window laminate from the vacuum bag;

inspecting the window laminate for damage or defects;

removing at least one of an outer nonstructural glass ply or an inner nonstructural glass ply upon determining damage or a defect in an adhesive ply of the window laminate;

removing the damaged or defective adhesive ply;

replacing the damaged or defective adhesive ply with a new adhesive ply;

removing damaged or defective heating wires and busbar and replacing new and functional wire heaters and busbar with the new adhesive ply; and

reattaching the removed at least one of the outer nonstructural glass ply or the inner nonstructural glass ply to the window laminate to complete a repair of the window laminate.

2 . A method for repairing a window laminate which has been delaminated and wherein moisture has entered into a void created by delamination, comprising the steps of:

placing the window laminate into a vacuum bag, sealing the vacuum bag closed and placing the vacuum bag containing the window laminate into an oven or an autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove moisture between plies of the window laminate;

removing the vacuum bag and the window laminate from the oven or the autoclave; and removing the window laminate from the vacuum bag;

inspecting the window laminate for damage or defects;

removing at least one of an outer nonstructural glass ply or an inner nonstructural glass ply upon determining damage or a defect in an adhesive ply of the window laminate;

removing the damaged or defective adhesive ply;

replacing the damaged or defective adhesive ply with a new adhesive ply;

removing a damaged or defective heat sensor and replacing the damaged or defective heat sensor with a functional heat sensor; and

reattaching the removed at least one of the outer nonstructural glass ply or the inner nonstructural glass ply to the window laminate to complete a repair of the window laminate.

3 . The method as recited in claim 2 wherein the replaced functional heat sensor is a circular wire coil heat sensor.

4 . The method as recited in claim 3 wherein the wire coil heat sensor comprises a series of wound wire in a coil on a flat plane.

5 . A method for repairing a window laminate which has been delaminated and wherein moisture has entered into a void created by delamination, comprising the steps of:

placing the window laminate into a vacuum bag, sealing the vacuum bag closed and placing the vacuum bag containing the window laminate into an oven or an autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove moisture between plies of the window laminate;

removing the vacuum bag and the window laminate from the oven or the autoclave; and removing the window laminate from the vacuum bag;

inspecting the window laminate for damage or defects;

removing at least one of an outer nonstructural glass ply or an inner nonstructural glass ply upon determining damage or a defect in an adhesive ply of the window laminate;

removing the damaged or defective adhesive ply;

replacing the damaged or defective adhesive ply with a new adhesive ply;

removing damaged or defective heating wires and busbar and replacing new and functional wire heaters and busbar with the new adhesive ply;

removing a damaged or defective heat sensor and replacing the damaged or defective heat sensor with a functional heat sensor; and

reattaching the removed at least one of the outer nonstructural glass ply or the inner nonstructural glass ply to the window laminate to complete a repair of the window laminate.

6 . The method as recited in claim 5 wherein the replaced functional heat sensor is a circular wire coil heat sensor.

7 . The method as recited in claim 6 wherein the wire coil heat sensor comprises a series of wound wire in a coil on a flat plane.
