“…In SMA composites, SMA can be deformed and returned to its original shape by its phase transformation. As common fiber-reinforced plastic composites (FRPs), SMA composites are highly susceptible to internal damage, which is generally caused by external static and dynamic mechanical behaviors, such as the flexing, fatigue, and the low-velocity impact on composite structures [ 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. All the load could cause barely-visible damages in SMA composites, and the surface may appear to be safe and sound upon visual inspection.…”

In this article, hybrid composite laminates with shape memory alloy (SMA) and glass fiber (GF) as the reinforced phase, and epoxy resin as the host material, were manufactured by vacuum-assisted resin injection (VARI) processing. The SMA wires were embedded into the GF/epoxy composites with three kinds of modes. The effect of SMA content and the position on the flexural, low-velocity impact performance of the hybrid composite laminates was investigated. It was found that the bonding performance between the SMA wire and the host material is the key factor that determined the final overall performance of the hybrid composite laminates in both the static and dynamics tests. Based on these experimental phenomenon, we further carried out the fiber pull-out experiment to improve the interfacial shear strength between the SMA and epoxy resin. It was found that the interfacial performance could be enhanced significantly by adding nanoparticles in the interface phase.

Lamb waves provide sensitive and effective approach for nondestructive inspection of large-scale composite structures. Traditionally in Lamb wavebased damage detection systems, the piezoelectric (PZT) wafer transducers are attached on the surface of composite components. However, surfacebonded PZT wafers are fragile, and they may lose serviceability when external load happens. In this paper, numerical and theoretical investigations are firstly carried out to analyze the Lamb wave features generated by PZT wafers that are located in the mid-thickness of a thin-walled plate. Subsequently, the authors integrate the PZT wafer arrays in woven glass fiber reinforced epoxy (WGF/epoxy) laminates with stacking sequence of [90 /0 ] 4 . It is found that the approximate single S0 Lamb wave mode is generated by the built-in PZT wafers. This makes the received signals very simple and easy to be interpreted. Utilizing the signals obtained by the built-in and surface-bonded PZT wafer transmitter-receiver arrays, damage localization algorithms that considered the slowness profiles are compiled to help locating the defects. The compared results demonstrate that the built-in PZT strategy has great potential for quantitative non-destructive evaluation of composite structures.
