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.
Claims2
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;
- 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.
