TERFENOL-D Lamination Process Cost Reduction

TL;DRAbstract

Abstract : The process of manufacturing laminated TERFENOL-D is costly and time consuming. This Phase I study was aimed at reducing the reject rate of the current lamination process and thus reducing the cost of laminated TERFENOL-D. Current stringent requirements call for infinite resistance between lamina. These requirements can lead to reject rates as high as 50%. Analytical calculations indicate that somewhat less than infinite interlaminate resistance is needed for eddy current reduction. This experimental study investigated the effects of less-than-infinite glue joints on eddy current losses. Test fixtures and methods were designed to compare solid rods and laminated rods with various interlaminate resistance. Initial results show a significant difference between solid rods and rods with less-than-infinite resistance. While there was some indication of a difference, the difference between infinite and less-than-infinite interlaminate resistance was within variance of the test pro
