LSP Technologies’ David Sokol explains non-destructive LBI process
In a recent webinar, LSP Technologies Director of Research David Sokol explains how the company’s non-destructive Laser Bond Inspection (LBI) technology can detect faulty bonds, including kissing bonds where the materials are in contact with each other but have no structural integrity.
Adhesive seals for composite materials pose a subtle challenge for quality control and safety, and that is how to detect problematic adhesive bonding without damaging materials or the adhesive bond itself.
A key step in the LBI process is to gradually increase the fluence, or power density, measured as Joules per square centimeter, for laser beams used to measure the integrity of composite adhesive bonds.
LBI readings show shock wave shapes that either reveal integrity in composite adhesive bonds or indicate clear failure in the bonds. The LBI process, at controlled levels, do not damage materials or compromise the integrity of healthily bonded composites.
