| This study explores the effect of auxetic unit cell geometry and wall thickness on the energy absorption performance of sandwich composites under quasi-static and low-velocity impact (LVI) loading. Four auxetic geometries reentrant, arrowhead, starshaped, and kiteshaped were 3D-printed using ABS material and first evaluated through quasi-static compression tests with three wall thicknesses (0.44, 0.62, and 0.80 mm). Results showed that thinner-walled specimens exhibited higher initial peak forces but more brittle collapse, while thicker-walled designs provided smoother force responses. The arrowhead geometry with 0.44 mm wall thickness exhibited the highest peak crushing force (6.413 kN) while 0.44 mm starshaped geometry showed the maximum specific energy absorption (SEA) value of 6.226 J/g. Based on these results, representative auxetic cores were embedded into GFRP/epoxy sandwich panels … |
