Abstract
This study focuses on failure response and energy absorption of woven ramie epoxy square composite tubes when exposed to the axial quasi-static compression test. Hand lay-up technique was used to prepare the rectangular composite tubes composed of 12 layers of ramie fabric with a thickness of 1.7 mm and 50-, 80-, and 120-mm-long tubes. The measured parameters were specific energy absorption, energy absorption, and peak load. The total energy absorption increased with the increase in the length of the tubes. The failure mode of the tested tubes was examined, and the mid-length and local buckling were considered as the main sources of failure. The woven natural ramie was used in the textiles for years. However, the results of this paper can be significant because of the limited research employing woven ramie as reinforcement for composites.
