Description

Bonded joints, such as the autoclave bond, are critical to the performance of weapon systems. A nondestructive method to assess the integrity of these bonds is needed to certify the weapon for extended life. This project is developing ultrasonic technologies for bond quality assessment. Existing ultrasonic technology easily maps totally unbonded areas in a bond line but does not measure the quality of the bond. We are extracting information from the ultrasonic signals to quantify the mechanical. properties and assess the durability of the bond. Our approach is based on advanced signal processing and artificial intelligence techniques that process information ... continued below

Description

Bonded joints, such as the autoclave bond, are critical to the performance of weapon systems. A nondestructive method to assess the integrity of these bonds is needed to certify the weapon for extended life. This project is developing ultrasonic technologies for bond quality assessment. Existing ultrasonic technology easily maps totally unbonded areas in a bond line but does not measure the quality of the bond. We are extracting information from the ultrasonic signals to quantify the mechanical. properties and assess the durability of the bond. Our approach is based on advanced signal processing and artificial intelligence techniques that process information from the ultrasonic signal after it interacts with the bondline. Computer algorithms recognize variations in bond quality from the acoustic signals. The ultrasonic signal processing and bond classification software will be installed on ultrasonic scanners at the appropriate sites.
