This study aimed to investigate the lateral crashworthiness performance of thin-walled circular glass fiber-reinforced epoxy (GFRE) tubes filled with various silicon carbide (SiC) nanoparticles weight percent (wt.%). The wet wrapping hand layup process was used to create GFRE tubes that were filled with 1, 2, 3, and 4 wt.% of SiC. For the laterally loaded tubes, the crushing load and absorbed energy versus displacement responses were displayed. In addition, deformation histories were monitored. As part of the crashworthiness analysis, the energy absorbed (EA) and specific absorbed energy (SEA) were evaluated. Two parameters of the Weibull distribution were working to evaluate the experimental results statistically. Overall research exposed that up to 2 wt.% of SiC, both EA and SEA are improved; after that, a visible reduction is observed.
