TERFENOL-D Lamination Process Cost Reduction

Award Year / Program / Phase:
1998 / SBIR / Phase I
Award Amount:
$69,988.00
Agency / Branch:
DOD / NAVY
Principal Investigator:
Dr. Julie Slaughter
Abstract:
All high performance TERFENOL-D sonar devices require the drivers to be laminated for eddy current control. The process of laminating TERFENOL-D to present interlamina resistivity requirements results in low yields due to considerable material loss and is, therefore, a wasteful process. The… More
