摘要： Inspection methods and systems for detecting leaks in a vacuum bag assembly used in the manufacture of a composite part based on spraying helium over the vacuum bag and detecting the helium drawn by the vacuum inside the vacuum bag through a leak. The inspection methods comprise creating a local helium atmosphere in a chamber over the vacuum bag assembly by zones, following a programmed zonal sequence, for a first leak detection test of each zone and a subsequent second leak detection test if the first test gives a positive result. The inspection systems comprise a helium spraying system and helium detecting equipment arranged to implement the inspection methods.

摘要： A system for testing bonded joints that comprises a swing tool, an actuator, pressure measuring device and a first fixing arrangement. The actuator of the system is configured to apply a compression force or a traction force on the swing tool in order to separate two elements, and the pressure measuring device is configured to measure the force applied on the swing tool. A method for testing bonded joints using the system is also provided.

摘要： A method of manufacturing T-shaped stringers made of composite material, including a second shaping step for shaping laminates into L-shaped preforms, which includes providing a set of tools formed by a fixed tool comprising a lower portion and an upper portion, and a moveable tool comprising a lower element and an upper element. It also includes the segment of the laminate intended for the foot of the preform being located between the lower portion and the upper portion of the fixed tool, and the segment of the laminate intended for the web of the preform being located between the lower element and the upper element of the moveable tool. It further includes vertically moving the moveable tool to progressively bend the web of the preform supporting it on a vertical wall of the fixed tool. The end of its web adopts a rounded shape.
