• Tubular braid
• tensile modulus
• monofilament yarn
• multifilament yarn

In the first part of this series, an analytical model was proposed for predicting the tensile modulus of tubular braids using energy method. The aim of this study is to perform experimental effort to evaluate the previous generated model. For this purpose, two types of yarns namely monofilament and multifilament yarns were used to produce tubular braids. The bending rigidity and tensile modulus of yarns were obtained in order to be used in the mentioned model. Also, the geometrical parameters of braids, i.e. braid angle, length of the unit-cell, and length of the yarns in the unit-cell were measured. Using the proposed model, the tensile modulus of braids was calculated. On the other hand, the tensile modulus of provided samples was measured by means of INSTRON tensile tester and compared with theoretical values. The results showed that the proposed model in Part I of this series is capable of predicting tensile modulus of braids with different structure, adequately.
