Large component non-destructive inspection: vision-based detection of defects and material properties
A vision inspection system for non-destructive inspection that identifies material properties such as composite fiber directionality, thermomechanical response and residual stress, as well as defects including microcracking, delamination and kissing bonds. The process causes no damage to components and improves measurement speed over other NDI processes.
The problem
Nondestructive inspection (NDI) is a vital tool for industries to support defect detection, material characterization, and overall processing quality control. Existing NDI technologies are costly, provide slow inspection and analysis, and are not applicable to all types of manufactured components.
The solution
Researchers from the University of Tennessee have developed a vision inspection system for applications in NDI. This system identifies material properties, such as composite fiber directionality, thermomechanical response, and residual stress. This technique also identifies various defects, including microcracking, delamination, and kissing bond defects. This process causes no damage to the components and has an improved measurement speed from other NDI processes.
Benefits
- Cost-effective inspection that improves efficiency of NDI processes
- Able to be directly integrated into existing manufacturing lines
- Compatible with large components
- Applicability in a wide range of industries and applications, including aerospace, wind turbines, composites, defense, and transportation
