GKN developing laser-based, automated composite repair system

Sample of plies removal techniques...

Well just want to share latest technology update for composite repair... Cool techno! I love composite!

GKN Aerospace (Isle of Wight, U.K.) reportts that it is harnessing leading-edge laser technology to automate the repair of composite structures. The company says that the repaired structure has the strength of current manual repair but is achieved with greater consistency and 60 percent cost reducton.

With program partners SCLR Lasertechnik GmbH (SLCR), GKN Aerospace has installed the first prototype robotic machine using laser technology to remove damaged composite structure on aircraft. The new robotic cell, housed at GKN Aerospace’s composites research centre in the U.K., replaces the time-consuming, manual grinding away of damaged structure with a precise, contact and vibration-free laser removal process

John Cornforth, head of technology at GKN Aerospace, comments, “With the first installation of this prototype equipment we are now commencing work on extending the ability of this new process to handle various shapes and sizes of structure. We believe this process has enormous potential; composite materials increasingly dominate the airframe meaning their reliable, effective repair is critical for operators and the industry alike. This technology will allow the efficient, cost effective and high quality preparation of almost any composite assembly for repair.”

Olav G. Schulz, managing director of SLCR, adds, “The newly designed system is the outcome of more than two years intensive collaboration and we are proud of the results achieved already. It is strong motivation for us to continue this program with GKN Aerospace and we invite potential users to participate.”

The new process uses lasers to remove damaged material, leaving the remaining fibers and resin intact. The technique applies no force or vibration onto the structure and so has no detrimental impact on its overall strength or integrity. The affected area is left clean and ready for repair using a replacement patch which is cured in place using a localized heating mat. - end

Comments : Awaneer :)

Nice techno right? The removal plies process in Composite repair is THE MOST unpleasant... time consuming... stressful... So if you can have automated plies removal than it will be great and wonderful!

Sample of plies removal using grinder+peeling... can take up to 5-6 hours to complete.

Current repair method used grinder to remove plies or peeling method. Well for me I like peeling method because it is dust free, easy and precise control on the step method removal without damaging underlying plies.

So, welcome to the club new techno! Cheers!
