Abstract
Thin-walled bi-tubular composite structural elements have been recently utilized as one of the significant energy absorbing elements in automotive and aircraft manufacturing industries to enhance the crushing features of the vehicles by maintaining their light-weight characteristics. This research paper aims to examine the crushing and energy dissipating features of double circular carbon fabric epoxy composite tube structures exposed to axial impact force. The recommended double circular carbon fabric epoxy composite tubes were made by hand layup technique. The successfully fabricated tubes were tested under impact loading with a constant impactor mass of 100 kg and varied impact speed of 8 m/s and 10 m/s. The outcomes revealed that the tubes having 4 layers at 10 m/s velocity gained better energy than the other tube configurations considered in this study. The overall results associated with the circular carbon fabric epoxy composite tubes highlighted the benefits of utilizing these tubes in the aircraft and automotive manufacturing industries.
