Sample positioning device for shear performance testing, testing device and testing method

By designing a sample positioning device for shear performance testing, the problems of fixture eccentricity and bending moment are eliminated, ensuring that the sample only bears pure shear load. This solves the accuracy and reliability problems of interface testing of secondary molded composite materials and achieves efficient test results.
