... in response to a magnetic field. These materials are made of a magnetic filler, such as Terfenol-D sensors, embedded in an elastomeric matrix. Magnetostrictive carbon fiber reinforced polymer (MagCFRP) is a self-sensing structural health composite material that is magnetically activated by an external...

Scanning on a Thin Slice: An Examination of a Magnetostrictive Sputtered 3D Printed Carbon Fiber Composite

Christopher Nelon, Brandon Williams, Oliver Myers, Asha Hall, Dereje Seifu
Proc. ASME. SMASIS2023, ASME 2023 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, V001T01A008, September 11–13, 2023
Publisher: American Society of Mechanical Engineers
Paper No: SMASIS2023-111036

... for safely depositing thin films of Terfenol-D, a highly pyrophoric magnetostrictive material when utilized in micro-sized particulate form, onto the surface of substrates. The sputtering process deposited magnetostrictive thin films onto a 6-millimeter diameter indentation surface in the gage area of 3D...
