Hi Denny, Laser Shearography can be used to detect kissing bonds and works well with GFRP. Using pressure or thermal excitation will open the bond and the displacement will be measured on the surface. The limitations will be the thickness, depth and size of the kissing bond.
There's some more info here: http://www.dantecdynamics.com/Default.aspx?ID=665

Non Contact Ultrasound, Phased Array Technique and Digital X Ray methods can be used to detect kissing bonds at GFRP / CFRP and Sandwich cores

For any further detail contact us.

Hi Denny,

Our company offers Ultrasonic systems that are capable of detecting kissing bonds in GFRP and GFRP Sandwich. If you have a sample you want to send us, we would be happy to run an evaluation test and show you the results. Please contact me if we can be of assistance.
