Abstract

The present research aims to evaluate the initial crashworthiness characteristics of resin-coated 3D-printed Thin-Walled Multi-Cell Structures (TWMCS) are affected by annealing parameters, specifically temperature and time, during quasi-static compression. The optimal parameter combination, determined through the Signal-to-Noise (S/N) ratio and analyzed using Analysis of Variance (ANOVA), identified key factors that have a substantial impact on the crashworthiness performance. Resin coating applied to TWMCS polymer tubes results in a substantial increase in Specific Energy Absorption (SEA) values, exhibiting a 41% improvement compared to tubes without resin coating. Optimal annealing conditions for SEA were found to be 80°C for 40 minutes, and the optimal conditions for achieving maximum Crushing Force Efficiency (CFE) were determined to be at a temperature of 80°C for 70 minutes. The combined application of resin coating and annealing leads to a 57% increase in SEA compared to specimens without either treatment. This study identifies new prospects for improving TWMCS with higher energy absorption capabilities. These improvements have the potential to enhance passenger safety and strengthen the infrastructure of transportation.
