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
