Imparting controllable flexural rigidity into a material system is one of the key motivations for the design of intelligent materials for structural applications. In this direction, shape memory alloy (SMA) reinforced polymer composites have enormous potentials for active shape and vibration control of systems related to aerospace, automobile, and energy harvesting applications. The primary motivation of reinforcing SMA wires into a composite is to actively change the composite stiffness or elasticity through thermo-mechanical as well as electrical/magnetic stimulation. The SMA -reinforced hybrid composites are found to be able to adapt their shape, which may also improve the specific strength, vibration damping, and self-healing capability by utilizing shape memory effect and pseudoelastic behavior of the SMA. In this paper, we intend to provide a comprehensive review of all SMA -reinforced composites available today in the open literature and a critical assessment of the technology. Currently, shape memory alloys in the form of long fibers (wires), ribbons, short fibers, and particles are used for hybridizing the reinforcements in composites. Continuous SMA fiber embedded composites are generally used for shape control of structures. However, it has difficulty in obtaining suitable interfacial characteristics required for actuation. The discontinuous SMA embedded composites have scope for modifying such active properties. The work presented here gives an overview of the concepts of design, development, and modeling of continuous and discontinuous shape memory alloy embedded composites for advanced smart composites.

“…The aim is to manufacture SMA-based composite panels for the reduction of the sonic fatigue in aeronautic structures. Moreover, in [ 69 , 70 , 71 , 72 , 73 ] the superior performance in terms of energy absorption and impact response of Shape Memory Alloy Hybrid Composites (SMAHC) is assessed. Other applications of SMA can be related to SMA wires embedded in complex wing structures [ 74 , 75 , 76 ], while in [ 77 ], SMA wires interact with a supportive system of pins and springs to actuate an articulated control surface.…”

The development of structures able to autonomously change their characteristics in response to an external simulation is considered a promising research field. Indeed, these structures, called smart structures, can be adopted to improve the aerodynamic performance of air and land vehicles. In this work, an overview and future applications of Shape Memory Alloys (SMA)-based smart structures are presented. The use of SMA materials seems to be very promising in several engineering sectors. Advanced SMA-based devices, designed to improve the aerodynamic performance of vehicles by modifying the shape of the spoiler and the rear upper panel, are briefly introduced and discussed in this paper. Indeed, a simplified model simulating the SMA mechanical behavior has been considered to demonstrate the feasibility of the introduced smart structures for adaptive aerodynamic applications. Numerical simulations of the investigated structures are provided as a justification of the proposed designs.

“…Guida et al [ 8 ] studied the impact dynamics of an SMA‐carbon fiber hybrid composite and found that SMA fibers considerably increased energy absorbing capacity of the composite. Similarly, Chang et al [ 9 ] concluded that embedding SMA wires into composite laminates can improve the impact resistance and reported an increase from 15% to 30% in absorbed energy. Dahnke et al [ 10 ] studied the influence of SMA addition into composites and observed an increase of the energy absorption capacity of the composite due to the high ductility of the SMA wires.…”

“…[1][2][3][4] A number of studies have shown that the use of SMA fibers in polymer composites can improve damping properties, impact resistance, and ductility of the composites. [5][6][7][8][9][10][11] Katsiropoulos et al [7] investigated the effect of superelastic SMAs in improving the damping behavior of polymer composites and observed that the incorporation of SMA wires can significantly improve the damping characteristics.

This article explores the tensile deformation and failure characteristics of a hybrid composite where microscale shape memory alloy (SMA) fibers and nanoscale graphene nanoplatelets (GNPs) were used to reinforce a ductile epoxy matrix. First, the GNPs were incorporated into epoxy system using a hybrid dispersion technique at various weight percentages ranging from 0.25 to 2.50 wt%. The mechanical properties of GNP composites were investigated using monotonic uniaxial tensile tests to failure and were compared to neat epoxy. The GNP concentration that resulted in highest enhancement in tensile properties of the epoxy was identified. Then, the GNP/SMA/epoxy composites were fabricated using a vacuum assisted hand lay-up technique. The composites were reinforced with SMA fibers at 50% volume ratio and an optimal GNP concentration was added. The tensile response of the developed composites was characterized using full-field strain measurements captured by a digital image correlation system, while simultaneously the thermal response of the composites was monitored through measurements of an infrared camera. The tensile properties, superelastic response, and failure mechanisms of the developed composites were discussed. Results shows that the developed GNP/SMA/ epoxy composites exhibit excellent superelastic characteristics with a maximum strength of 533 MPa and failure elongation of 12.5%.
