Abstract:

A method is disclosed for repairing laminates such as aircraft transparency windows in which two plies of the laminate have become separated and created a void. The method of the invention basically comprises the steps of selecting an adhesive having a viscosity sufficient to flow into the void formed between the two separated plies and then introducing an amount of the adhesive into the void such that the adhesive fills substantially all of the void thereby repairing the laminate. The preferred technique for introducing the adhesive into the void comprises the steps of filling a syringe with an amount of the adhesive, affixing a hypodermic needle to the syringe, and forcing the needle into the void of the delaminated area. The syringe is then operated to force the adhesive into the void until the void is completely filled with the adhesive.
