As the percentage of composites continues to increase in aerostructures, it becomes more and more critical to develop economical and effective inspection systems capable of ensuring quality for a variety of part geometries, as the inspection and rework times significantly impact throughput and capital equipment utilization. Current technologies for scanning the as-laid part topography for defects (e.g., gap, lap, end placement, and missing tow) of CFRP-based structures suffer from several limitations. Specifically, instruments based on these technologies experience high measurement dropout rates when applied to surfaces with high curvature, and the footprint of the sensor does not allow for adequate mounting on a highly articulating layup head.
In this presentation, we introduce an instrument designed specifically for in-process composites inspection that is currently being deployed in a field trial. The measurement technique is based on a robust technology which is not currently used for composite surface profilometry. We will discuss quantitative results based on extensive testing on a Fives VIPER Series fiber placement equipment made by Fives Cincinnati. We shall also discuss future steps to integrate this technology into comprehensive fiber placement closed loop control.
- Upon completion, attendees will be able to clearly understand the key enablers for a high performance in-process inspection system
- Upon completion, attendees will be able to identify the commercial inspection solution offerings and their strengths and weakness
- Upon completion, attendees will be able to develop a return on investment model for implementing inspection in their own factory
Why Is It Important?
Fives has been working for ten years on perfecting the technology for in-process inspection and has trialed and tested many solutions. This presentation will outline our results and give a good insight into what is required to deliver a state-of-the-art production inspection solution.
