Problems solved by technology
The structure of the system designed in this patent is relatively complex, and its test method is not suitable for flexible fiber-reinforced films
First of all, it is difficult to simulate the real working conditions of the flexible film material by manufacturing defects on the test material. In addition, if the fiber-reinforced flexible film material is artificially manufactured in advance, the strength of the defect will be greatly reduced, and the material will basically be in failure. state, this pre-destructive test method is not suitable for flexible fiber reinforced film materials

Description
technical field [0001] The invention belongs to the field of mechanical measurement and designs a biaxial stress fatigue loading test device for a flexible fiber reinforced film. The test device can simultaneously load non-interfering stress loads on the warp and weft directions of the flexible reinforced film material to measure its fatigue characteristics in biaxial stretching. The designed device can load the required basic stress and cyclical stress for the warp and weft directions of the flexible film material sample. The structure of the test device is simple, the test operation is simple and easy to use, it can simulate the biaxial fatigue characteristics of flexible fiber reinforced membrane materials under real load conditions, and provides a simple and reliable way for designing and testing the fatigue characteristics of flexible fiber reinforced membrane materials . Background technique [0002] In the process of new product structure design and new material dev...
