  Abstract

This article experimentally examines the crashing performance and failure mechanisms of jute fiber (J)-reinforced epoxy/aluminum (Al) hybrid pipes with circular cutout. Wet wrapping by hand lay-up was used to manufacture the designed hybrid pipes, and they were tested under quasi-static axial loads. As crash indicators, hybrid pipes' initial peak load (Fip), total absorbed energy (AE), mean crash load (Fm), specific energy absorption (SEA), and crash force efficiency (CFE) were evaluated. On these indicators, the effect of the number J-plies (P) and circular cutout parameters, i.e., diameter (D) and number (N) of holes, was evaluated. To make statistical predictions about the crash indicators, mathematical regression equations were used. Furthermore, the variance of analysis (ANOVA) was also adapted to determine the percent contribution of each parameter to crash indicators. The experimental outcomes revealed a significant relationship between the studied parameters and the crashing performance as well as the failure mechanisms. Results showed that D is the maximum impelling parameter on the values of Fip and AE with contribution percents of 50.73 and 62.18%, respectively, followed by P with contribution percents of 37.76 and 27.91%, respectively. While P is the highest influencing parameter on the values of Fm, SEA, and CFE with contribution percents, respectively of 59.87, 45.77, and 61.98%, followed by D for Fm and SEA with contribution percents of 34.66 and 34.83% but N for CFE with a percent of 27.05%.
