Compression after high-velocity impact behavior of pseudo-elastic shape memory alloy embedded glass/epoxy composite laminates

The compression after high-velocity impact (CAI) behavior of pseudo-elastic shape memory alloy (PE-SMA) embedded glass/epoxy composite laminates manufactured via vacuum-assisted resin infusion (VARI) technique was investigated experimentally. High-velocity tests were performed on the composites using an in-house build gas-gun set-up at four different velocities (70, 85, 95, and 105 m/s). To elucidate, series damage events undergone under impact, a high-speed camera used. Quasi-static compression-after-impact to evaluate tolerance subjected impact. Real-time progression during CAI as well extent characterized by 2D Digital Image Correlation (DIC) technique. Three types embedment configurations PE-SMA wire, namely, with length variation (35, 70, 150 mm) also without anchors, test results show that ballistic limit anchored 35 mm is 72.72% higher than homogeneous composites. indicate based have better respect ones 70 m/s. In contrast, velocities, delamination area decreases in homogenous due more localized present compressive strength.
