DolphiTech announces breakthrough on Drilled Hole inspectionDolphiTech AS12, Raufoss, Norway
DolphiTech announce today that the DolphiCam Ultrasound NDT Camera System has received new functionality for drilled hole inspections on CFRP laminates (Carbon Fiber Reinforced Plastic).
“We have done important breakthroughs on the DolphiCam system towards inspection of drilled hole flaking and delamination. The improvements include functionality for better detectability as well as technical solutions for easy use and interpretation of results”, says Eskil Skoglund, Head of Development at DolphiTech. “We are now comfortably able to detect flaking and delamination along the drilled hole as small as 2 millimeters (0.08″), and only 1-2 plies from the laminate front- and back walls. This really enhances DolphiCam even further as an inspection tool for drilled holes.”
“Defect-free holes are critical for optimal strength in CFRP structures. We are very happy to offer a rock solid point-and-click NDT solution for drilled holes. With the new functionality and our unique dry coupling, manufacturers and in-service organizations will benefit from drastically lowered inspection times and improved inspection quality”, says Jan O. Endrerud, CEO of DolphiTech.
The new functions will be made available as a software upgrade to existing customers.
