COMPOSITESWORLD Expo Conferences feature beginner, advanced tracks

COMPOSITESWORLD Expo 2008, Sept. 2-5 in Schaumburg, Ill., features a conference with a track for those new to composites and a track for composites industry veterans. 

The debut of COMPOSITESWORLD Expo 2008 is fast approaching, Sept. 2-5 at the Renaissance Schaumburg Hotel and Convention Center in the Chicago suburb of Schaumburg, Ill. The Expo features a two-day, two-track conference Sept. 2-3, followed by the show itself, Sept. 3-5. The conference includes a beginner track to introduce composites materials, design and processing to those new to the industry, as well as an advanced track for composites industry veterans.

Below is an abstract from the advanced conference track:

High-Resolution, Low-Cost Ultrasound Camera for In-Service Composite Defect Inspection

Ultrasound is arguably one of the best nondestructive methods for finding internal defects within composites. However, current single point ultrasonics is a slow laborious process that requires a highly trained specialist. Accidental impact damage cannot easily be found and quantified without complicated equipment which requires extensive training. A quick and easy inspection of aircraft composites in the field is badly needed. Imperium, Inc. and Boeing are jointly reporting on the results of the use of a novel ultrasound camera for in-service NDT of composites that alleviates these limitations. The ultrasound camera is based on a patented imaging array that generates real time ultrasound images over an area, similar to a conventional camcorder. A non-specialized technician can easily understand the resulting imagery. Each frame, presented at TV rates, presents a C-scan image over an area. A handheld probe is placed against the target under study and real time subsurface imagery appears on a display. The system is fully portable and requires little training. Compared to other NDT methods, the advantages of this include very rapid, image-based delamination assessment and crack detection. During this paper we will report on Boeing’s implementation ofa device as describe some results that the device has provided.
