Carbon Fiber Parts Inspected With Wide Line Portable Laser Scanner

Compositech is an ISO 9001 certified company present on the market since 2004 dealing with the production of parts in composite materials, typically carbon fiber prepreg in autoclave, mainly for the automotive and motorsport sectors. In order to respond with short timescales, guarantee customer confidentiality and security of the data, and to guarantee the highest standards of quality control of the processes that can influence it, all production takes place within its own building structure.

Before opting for a Krean Ace Skyline arm, Compositech had the chance to try out a 3D photogrammetry inspection system. But this option, deemed too slow because of the tedious job of placing lots of stickers on the parts before scanning, was quickly rejected. The Ace arm, by contrast, is always ready to scan at a moment’s notice – no pre-heating or positioning necessary. The difference in productivity is even more evident on large parts.

Ace 3-meter arm with a Skyline Wide scanner for the following applications:

  • Checking for distortions caused by residual curing stresses. All of the part’s surfaces are scanned and compared with the CAD file using color mapping in Polyworks.
  • Geometric inspection of the positions of drilled holes, center-to-center distances, etc.
  • Inspection of assemblies of different carbon parts, often glued together. There may also be metal inserts.

All individual parts are systematically inspected. For series production, the first part is inspected, then one part in every 100 thereafter.

With the Skyline Wide scanner, the surfaces can be scanned very quickly. The scanner’s frequency allows fast, fluid hand movements while its very wide 200 mm laser line minimizes the number of passes over the part. These features save significant amounts of time when inspecting large parts. In addition the 3D Skyline scanner easily handles black carbon surfaces.

“The speed and ease of use of the Ace Skyline arm have allowed us to significantly increase our productivity across the inspection phases” states Fabio Panarelli, Quality Inspector.
