Latest Patents

Campagne holds a patent for a method of assessing bond integrity in bonded structures. This technique utilizes acoustic detection to identify disbonds within bonded structures. By employing thermal excitation of the surface, it induces lifting and membrane vibration, making it applicable to laminates, coated structures, foam core structures, and honeycomb structures. Notably, this method does not require access to both sides of the bonded structure, which adds to its practicality. A large etendue interferometer is utilized for surface displacement measurement, allowing for detailed analysis of frequency or amplitude to determine the existence of a disbond. Furthermore, traditional pulse-echo time analysis can be used to ascertain the thickness of the disbond, potentially enabling the detection of stick bonds.
