Abstract

Despite substantial research into smart materials and structures technology, the integration of magnetostrictive materials into fibre reinforced laminated structures to provide capabilities such as vibration suppression has been limited to date. In this work, magnetostrictive Terfenol-D is inserted into unidirectional glass and carbon fibre reinforced polymer laminates. The strain developed in the laminates due to the magnetostriction of the Terfenol-D was observed and found to be a maximum of 0.11% normal to the fibre direction for a 3 ply carbon fibre laminate with the Terfenol-D recessed within a mid-ply cut-out. This demonstrates the actuation potential of Terfenol-D within a smart structure.
