摘要: Shape memory alloy (SMA) wire embedded composites (SMAECs) are widely used as morphing structures in small-size and high-output systems. However, conventional SMAECs cannot keep deformed shapes without additional energy. In this paper, a new kind of smart structure named the woven type soft composite (SSC) beam is introduced, which not only capable morphing, but also maintaining its shape The SSC consists two parts: wires matrix. selected nitinol (Ni–Ti) SMA glass fibers, while matrix part polydimethylsiloxane (PDMS). order to evaluate performance areas such in-plane deformation, blocking force repeatability, beam-shape specimen prepared size 100 mm (length) × 8 (width) ×3 (thickness). fabricated achieved 21 deformation 16 retention. Blocking was measured using dynamometer, about 60 mN. repeatability test, it recovered almost same position when cooling time 90 s more. Consequently, can be applied bio-mimicking, actuators, consuming less energy than traditional SMAECs.
