An Ample Review on Compatibility and Competence of Shape Memory Alloys for Enhancing Composites

Abstract

The name shape memory alloy (SMA) reveals its behavior of being an accurate heat-sensitive material in changing its shape based on the temperature. This ample review concentrates on the current scenario of including SMA in polymer matrix composites to achieve desired objectives. Polymer-based shape memory alloys are termed shape memory polymers (SMP), and they consist of deformable materials that are able to switch between their original shapes and temporary shapes, which can be generously designed. SMPs could be classified as smart materials by considering their low density, good biocompatibility, excessive deformation etc. On the other hand, many engineering applications of SMP uses have limitations and disadvantages. In this regard, the importance of SMPs has been analyzed based on the following aspects: synthesis method, fiber reinforcement, parameters that affected the polymer-based SMA, and implementation of multifunctionality materials. Fiber-reinforced polymer composites have more responsibilities for expanding interest in current innovative research and expected mechanical applications because of their significant space compared with conservative materials. A polymer composite presents effectively adaptable product properties, expected high strength-to-weight ratio, high flexibility in the manufacturing process, high corrosion resistance, and easy fabrication at a lower cost.
