Abstract
An in-situ double vacuum debulk (DVD) composite repair system designed to produce partially or fully cured autoclave-quality hot-bond composite repairs on contoured structures. The system provides vacuum pressure for hot bond repairs to be performed on flat and contoured structures using one set-up capable of debulking (partially curing) and then fully curing composite repairs on composite and metallic aircraft structures. The use of in-situ DVD also eliminates handling of the patch/adhesive when transferring from an off-aircraft DVD chamber to the repair site on the aircraft. This can increase the probability of successful repairs because the possibility of contaminating and misaligning the adhesive and repair patch are eliminated.
