- Evaluating in‐plane shear properties of bamboo textile‐reinforced polymer using the Iosipescu, V‐notch rail shear, and ±45° laminate tension tests Chun‐Wei Chang Shyue‐Cheng Li Zhu‐Min Tang Feng‐Cheng Chang Polymer Composites AbstractIn this study, the in‐plane shear behavior of bamboo textile‐reinforced polymer with twill 2/2 structure were evaluated using the Iosipescu, V‐notched rail tension, and ± 45° laminate tension tests. We analyzed the behavior of the polymer under various shear strains and loading conditions in these tests using various strain measurement tools, including digital image correlation. We discovered that the shear modulus and shear strength varied significantly depending on the loading modes and testing methods. The in‐plane shear modulus G12 (or GLT) values (1.94–1.25 GPa) differed among the three tests because of the different loading modes, load response characteristics, and fracture modes of the matrix and bamboo. The rail test conducted in the tension loading mode produced the ideal contours of pure in‐plane shear. We also found that the size of the woven unit relative to the gauge length plays a critical role in determining the stability of the measured strain value. This study validated the influence of loading mechanisms and structural characteristics on the measured shear properties of the biocomposite materials.Highlights In‐plane shear obtained using three distinct test methods G12 of bamboo‐reinforced polymer is 1.94–1.25 GPa Loading modes affect shear modulus and strength Woven unit size crucial in measuring shear strain 10.1002/pc.29643 http://onlinelibrary.wiley.com/termsAndConditions#vor
