A strain sweep test was performed on the natural fiber composites in order to establish the linear viscoelastic regime and to characterize the strain dependent viscoelastic properties of the samples, 0.002 was a chosen strain from this linear regime. After which a dynamic frequency sweep tests were performed using this strain amplitude of 0.002. The complex torsional modulus (G⁄) calculated using Eq. (2) below can be assimilated to the torsion modulus [26]:
