Effect of alumina nano‐particles on collapse behavior and energy absorption of laterally loaded <scp>glass/epoxy</scp> composite tubes

Abstract Due to its exceptional mechanical and crashworthiness properties, lightweight nanocomposites have recently been used more in aviation, defense, nautical, automotive applications. Nanocomposite cylinders could be effectively employed this respect as energy‐absorbing components for decreasing the impact energy during vehicle crashes. The current work examined response of nano‐alumina (Al 2 O 3 ) filled glass fiber reinforced epoxy (GFRE) composite tubes using quasi‐static lateral compressive loads. Crushing profiles crush force–deformation curves all representative samples were recorded discussed. total absorbed (AE) specific (SEA) tested specimens assessed. Furthermore, a multi‐attribute decision making (MADM) technique known complex proportional assessment (COPRAS) was compute optimum nano‐Al wt%. Based on experimental results, addition 1, 2, wt% enhanced AE by 7.69%, 18.14%, 51.21% SEA 3.43%, 13.98%, 39.84%, respectively. While deteriorations 6.59% 17.41% SEA, respectively, with 4 .
