Abstract
One class of smart materials receiving increased attention is SMA composites using embedded Nitinol wires as actuators. Previous research has been limited to wires trained for one-way shape memory behavior. The objective of this paper is to assess the feasibility of using two-way shape memory training of Nitinol wires for their use as embedded actuators in SMA composites. Two-way shape memory training is discussed and the evolution of the memory effect with training cycles is presented. The effect of the composite cure cycle on trained behavior is also investigated. The manufacturing of two SMA composite beams is detailed and their quality is assessed using optical microscopy and image analysis. Voids are shown to concentrate near the embedded wires. A comparison is made between the quality of the beams using hot pressing or autoclave processing methods.
