Journal Article 2019 02 27 In the first part of this series, a straight-line geometrical model was generated for Queen’s Cord warpknitted fabrics as reinforcement of the composite. In this part, the Rule of Mixture (ROM) was modified to calculate the elastic modulus of composites reinforced with Queen’s Cord fabrics using the straight-line model. For this purpose, the geometrical model was divided into different segments, and their angle with the direction of applied force was obtained. Considering the alignment of each segment, the effective length of different segments of the unit-cell of fabrics was calculated. Using the effective length, an orientation coefficient was defined for tensile modulus of fibers in ROM. In order to evaluate the modified ROM, nine types of composites were fabricated using produced Queen’s Cord fabrics. The results showed that modified ROM is closer to experiments than previous modifications. http://www.itast.ir/article_83099_1c1704c7601fcdb79cf1ba3d3cb72e91.pdf
