Shape Memory Polymers with Embedded Nichrome Wire

Scott Rauscher M.S. from the University of Pittsburgh is entitled Testing and Analysis of Shape-Memory Polymers for Morphing Aircraft Skin Application.  His thesis focuses on the development of aircraft wings that can change geometry to create optimal behavior during all flight times.  He approach is to create a structurally reinforced shape memory polymer material with the reinforcement containing an embedded heating element.  For the heating element, he incorporates Nickel-chrominum wire.  There are two tables from his thesis below that give the properties of Nichrome wire:
