Abstract
This research aims to study on the increase the number of sectional sides on the energy absorption capacity of fiberglass composite polygon tubes under torsional moment. The fiberglass composite polygon tubes include square, hexagonal, octagonal, decagonal, icosagonal, tetracontagonal, hexacontagonal, octacontagonal, and circle tubes. The results can be concluded that the comparisons between experimental results are good agree with finite element results. Then, it can find that the value of the maximum torsional moment of empty and fiberglass composite square tubes have the lowest, next the maximum torsional moment increases with the number of sectional sides of tube increase and that of circle tubes have the highest. The results of the average torsional moment of all square tubes have the lowest and all hexagonal tubes have the highest, but other polygonal tubes have slightly change of average torsional moment. The value of torsional moment efficiency of fiberglass composite hexagonal tubes has higher than empty tube equal to 73.77% and 73.29%. It can also be found that the value of torsional moment efficiency of fiberglass composite hexagonal tubes at thickness 1 mm and 2 mm have similar values. Hence, in the design, the fiberglass composite hexagonal tubes should be chosen to increase the energy absorption capacity.
