A Multifunctional smart material system consists of two or more different smart material phases in the form of a hybrid system, in which every phase performs a different but necessary function. In this work, we show how thermally responsive Shape memory alloys (SMA) and Shape Memory Polymers (SMP) can be combined to form a Multifunctional Smart Material system (MSMS). The transformation temperatures Mf, Ms, Asand Afof SMA and the glass transition Tgfor the SMP play a critical role in designing such a MSMS. We illustrate how varying the Tgof SMP between the transformation temperatures Mfand Afof SMA results in a multi-state smart bias system with varying stiffnesses. In addition, we establish guidelines for the volume fractions of the individual constituents of such MSMSs to form "smart-bias" tools/devices. We further propose various ideas for smart devices that can operate through three temperature ranges, with one material constituent being passive and the other active at a given temperature. 2012 SPIE.
