Progress in the Reliability of Bonded Composite Structures

Improving Composite Bonds in Aircraft

The Surface Analyst™ technology has many of its roots in the CAI (Composites Affordability Initiative) program from the mid to late 1990’s.  This industry/government partnership comprised of a team charged with addressing the perceived risks and barriers to a more widespread use of composite materials in aircraft design. The collaboration included members from the Air Force Materials Laboratory, the Office of Naval Research, Bell Helicopter Textron, The Boeing Company, Lockheed Martin Corporation, and Northrop Grumman Corporation.

Evaluating Bonded Composites for Reliability

As part of our role, we worked with Boeing and AFRL to evaluate surface energy measurements as predictors of the bondability of composite surfaces. One of our partners at AFRL, Robert Crane, is a respected expert in techniques for non-destructive evaluation of composites. The Royal Society in London recently invited Bob to present a review of latest advances in non-destructive evaluation. He chose to highlight some of the work that BTG Labs has done more recently under the TRUST program.  Applied Composite Materials recently published this presentation  as an article titled “Progress in the Reliability of Bonded Composite Structures."
