This paper presents a study on the vibration characteristics of Ni-Ti wire inter-weaved glass fabric/epoxy composites.
The Ni-Ti pseudo-elastic wires were used as warp yarns and embedded in the fabric preforms with various weaving
methods. Dynamic Mechanical Analyzer (DMA) and vibration test technique were used to reveal the dynamical
behaviors of specimens in different frequencies of vibration. The storage modulus E', the loss tanδ, the natural frequency
f and damping ratio η were examined. The energy dissipation behaviors of the Ni-Ti pseudo-elastic wire, the geometry of
textile fabric was also studied. The effect of weaving method on the vibration behavior in Shape Memory Alloy (SMA)
based textile composites was considered. The results showed that: (I) the energy dissipation capacity of the wire could be
significantly improved by increasing the tensile strain and speed, but slightly affected by loading frequency; (II) the
woven of few Ni-Ti warps caused the increase of the storage modulus and the change of the loss tanδ. In the buckling
vibration, the damping effects of Ni-Ti pseudo-elastic wires vary with the woven structures. The compact woven
structure with proper Ni-Ti warp architectures would receive a small amplitude and good damping.
