Abstract

The present study employed experimental techniques to investigate the energy absorption capability of circular woven jute fibre reinforced epoxy composite tubes. Different configurations of circular perforation holes (from 2 to 8 holes) were used to cause gradual crushing of the composite tubes. The tubes were made using compression bladder moulding and three layers of woven bi-directional natural jute fabric, each with a wall thickness of 3 mm and a length of 100 mm. Each tube's deformation patterns and load-displacement properties were analysed using quasi-static compressive testing at the speed 10 mm/min. The research also looked at factors including total energy absorption (Et), specific energy absorption (SEA), crush force efficiency (CFE), peak load (Pmax), and average load (Pm). Results showed that perforated tubes exhibited up higher SEA and CFE compared to non-perforated tubes. The JRECC-8H configuration exhibited the highest performance, with SEA of 34.82 kJ/kg, CFE of 0.73, and a Et of 1.834 kJ, representing an improvement of over 95% SEA and 87% higher CFE compared to non-perforated tubes. The findings revealed that most composite tubes broke in a progressive manner, and the specific energy absorbed by the tubes increased with the number of perforation holes. The findings of this study are noteworthy since there has been little investigation into the usage of perforated tubes in energy absorption structures.
