20110232829METHOD AND A DEVICE FOR REPAIRING PARTS OF COMPOSITE MATERIAL OF AN AIRCRAFT - In order to repair a composite-material panel forming part of the external surface of an aircraft, a portable device is applied onto that surface, the portable device including an inflatable chamber consisting of a flexible and airtight membrane and a concave body of rubber-like material sealed with the membrane. The concave body incorporates an inextensible inner reinforcement. Pressurized air is introduced into the chamber via a valve. A further valve, which passes through the membrane in a zone of the membrane external to the chamber, is used to suck air from one side of the membrane to the other.09-29-2011
