Stiffness and vibrational characteristics of SMS/DER331 composites with shape memory alloy long fibers

SMA-composites are an adaptive composite in which SMA elements are incorporated into fiber reinforced epoxy composites. Many researches have been done on investigating the properties of shape memory effect and superelastic influence in SMA composites. However, little information available on t...

This observation indicates that the Young's modulus increases (1667.083MPa) at 2.4% fiber volume fraction of flexinol wire of SMAJDER331 compared to matrix Young's modulus (904.495MPa). The increase of temperature up to 75°C and 90°C lead to the recovery of stress and strain and therefore closed hysteresis achieved.
