Thermomechanical Behavior of a Composite Based on a NiTi Ribbon with a Magnetic Hybrid Polymer

A SMA ribbon is joined with a magnetic hybrid polymer in order to obtain a new composite material. The hybrid polymer is composed by nanoparticles of Fe2O3 coated by carboxymethyl cellulose (CMC), and embedded in a polymer matrix of polyvinyl butyral (PVB). In this work, the characterizations by DMA...

Description
Summary:A SMA ribbon is joined with a magnetic hybrid polymer in order to obtain a new composite material. The hybrid polymer is composed by nanoparticles of Fe2O3 coated by carboxymethyl cellulose (CMC), and embedded in a polymer matrix of polyvinyl butyral (PVB). In this work, the characterizations by DMA of the NiTi ribbon, the (Fe2O3-CMC)/PVB hybrid polymer and the composite material, are presented. Besides, the thermomechanical cycling at constant stress of the NiTi ribbon and the composite material are evaluated and compared; polymer acts as mechanical backing causing a reduction in shape memory properties of the composite material.
