To study the shear properties of the E-glass fiber reinforced polymer （E-GFRP）, the ±45° tensile test, the 45° off-axis tensile test and the interlaminar shear strength test were carried out on the E-GFRP. The in-plane （vertical and horizontal） shear strength, in-plane （vertical and horizontal） shear modulus and interlaminar shear strength of the E-GFRP material were studied. And the characteristics of the E-GFRP material shear failure were discussed. According to the existing calculation models for composite materials, the in-plane shear modulus of specimens were calculated and compared with the test results, to compare the prediction effect of each calculation model. The results show that the shear property parameters of the E-GFRP measured in the ±45° tensile test are more reliable than those measured in the 45° off-axis tensile test； among all the models, the predictive values of Halpin-Tsai prediction model and the formula recommended by Zhenming Wang agree well with the experimental data.
