Shape memory effect of polymeric composite materials filled with NiMnSbB shape memory alloy for textile materials

Abstract

The aim of the study was to obtain a smart textile material with shape memory alloys. NiMn-based shape memory alloy was produced by arc melting system for this purpose. Phase transition temperatures of the fabricated alloy were determined by using differential scanning calorimeter (DSC). The crystallographic structure of the fabricated alloy was characterized by x-ray diffractometer (XRD). The fabricated shape memory alloy was converted to the particle form and filled into polymer matrix to obtain shape memory effect of this polymeric composite material. Polymeric composites (PCs) were produced in film form and shape training of PCs were studied under different conditions. The shape memory behavior of samples was investigated into the water for fast response during applying heat. Damping capacity of composites was measured by using dynamic mechanical analyzer (DMA) according to temperature rising. The shape recovery was observed under certain stimuli on the SMA filled polymeric composites.
