Development of 4-element Generalized Maxwell Model for pure carbon nanotube and carbon nanotube-epoxy composite fiber

We try to represent the correlations for calculation of pure carbon nanotube (CNT) and CNT/epoxy composite fiber stress relaxation modulus in base of generalized Maxwell.4-element generalized Maxwell model (GMM) used and Gi and λi –the parameters of this model- acquired with genetic algorithm (GA). The model accurately predicts the correlation. Comparison between calculated modulus with the modulus from experimental outcomes show the conformity of the model with experimental outcomes of both pure CNT fiber and CNT/epoxy composite fiber, so we can see that generalized Maxwell is almost proper for modeling quasi static tests. Hence this model could be used for predict stress relaxation modulus of both pure CNT fiber and CNT/epoxy composite fiber with good agreement
