Exploring the role of shape memory alloys in advanced composite sandwich panels and laminates

Smart materials have garnered significant attention in material research due to their remarkable ability to react to external stresses and retain their original shape. This paper presents a systematic review of the integration of shape memory alloys (SMAs) into composite structures, underscoring a pioneering frontier in smart materials research. Analyzing a large number of research publications, the review offers critical insights into the latest trends and innovative approaches in embedding SMAs into composite structures. The analysis is methodically divided into two categories based on loading conditions: static and dynamic. This review not only highlights the significant potential of SMAs in composite applications but also identifies key research gaps and future directions. The main research gap is the potential of SMA implementation in the core structure of sandwich panels emerging as a particularly promising avenue for future research.
