TECHNOLOGY TRANSFER OPPORTUNITY: Method and Means to Analyze Thermographic Data Acquired During Automated Fiber Placement (LAR-TOPS-284)

NASA's Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses . THE TECHNOLOGY : Automated Fiber Placement machines (AFP) can be susceptible to tow-tape defects such as gaps and overlaps. These can reduce strength between 7% and 32%. Automated inspection is not fully effective, and current AFP systems rely heavily on visual based inspections of each ply layer to detect and correct these tape defects. The latent heat of the item under fabrication is used to create a thermal image of a just completed tape bond. The image is then analyzed to detect anomalies in real-time. The defect data can be used in a feedback process to guide the bonding operation and tag the defect location for subsequent inspection. Image processing is a key element of the successfully implementing the process. The image process technique used not only reduces processing resources (such as CPU usage, memory, etc.), but also allows for a number of standard time-based analysis algorithms, typical of flash thermography, to be applied to the data (the reconstructed sequence).
