Davis says the area of measurement can reach up to approximately 150 feet, making it ideal for identifying the horizontal and vertical location of material changes in large parts. Visualization software color maps the magnitude of measurement to the location of the fibers. As an example, bright red indicates load tension while bright blue typically shows areas of compression. So, a strike might show blue where the hit was and red surrounding it, depending on the part geometry. The user can adjust the color scale to identify what they are most interested in identifying.
These advances in NDE – and others on the horizon – take advantage of technological innovations and show promise for the composites industry. “These new methods of performing NDE to revise design, to make corrections to the manufacturing process and to analyze parts in the field are often headed for use in Industry 4.0 platforms,” says Dorworth. “It’s quite interesting to see how these advancements in NDE are reducing problems for the FRP industry.”
