In-situ quantification of membrane adhesion using advanced NDE methods
A cutting-edge inspection system utilizing phased array ultrasonic technology for real-time detection and quantification of adhesion areas in TPO membranes. This system offers immediate feedback, enhances quality assurance, and reduces rework costs.
Overview
This innovative inspection system uses advanced non-destructive evaluation (NDE) methods to quantify membrane adhesion in real-time. Targeted at Thermoplastic Polyolefin (TPO) coatings, the system integrates a patented aerospace-grade phased array ultrasonic technology with a hot air welder. It provides immediate visual feedback to operators about the adhesion uniformity of TPO membranes during installation. This user-friendly solution significantly enhances quality assurance by enabling instant verification of proper bonding, reducing rework costs, and ensuring industry compliance.
Technical specifications
- Utilizes phased array ultrasonic testing (PAUT) for precise measurement of TPO membrane adhesion width along seams.
- Provides high accuracy with capabilities to measure adhesive bondline thickness to within 0.002 inches.
- Archives inspection data for subsequent analysis, enhancing long-term quality control.
- Integrates with existing hot air welders, offering seamless visualization and archival of improperly adhered TPOs.
- Future development includes thermal mapping with software and controller integration for comprehensive inspection.
Technology readiness level
Currently at Technology Readiness Level 3, the system has been demonstrated in a laboratory environment. Ongoing development includes prototype refinement and field demonstrations to ensure robustness and user-friendliness. Future phases will expand capabilities with thermal mapping and model integrations, moving towards higher TRL levels.
