In this article, the performance of transversely loaded glass fiber reinforced epoxy (GFRE) tubular components containing carbon nanopowder (CNP) in terms of crashworthiness was investigated. The wet-wrapping by hand lay-up procedures were used to make GFRE tubes that included 0, 0.25, 0.50, 1, 2, 3, and 4 wt% of CNP. For the laterally loaded tubes, the crashing load and total absorbed energy (TAE) versus displacement responses were displayed. The histories of deformation were tracked in addition. As part of the crashworthiness analysis, the TAE and specific absorbed energy (SEA) were evaluated. Overall results demonstrated that CNP enhances both TAE and SEA up to 0.50 wt% of CNP; after that, a significant deterioration was noticed. CNP, at very low wt%, is considered a great choice for enhancing the crashworthiness performance of composite structures.
