[0002] TPU (thermoplastic polyurethane elastomer) composite fabric is a functional material made of TPU film and fiber substrate (such as nylon, polyester, etc.) through coating, lamination and other processes. Currently, the tear resistance of TPU composite fabric is mainly tested by manually cutting samples and fixing them on a tensile testing machine to detect the tensile force generated during the tearing process. These methods have the following shortcomings: 1. Because multiple tests are required to ensure the accuracy of the test, manual cutting of samples is cumbersome and requires multiple cuts on a piece of cloth, which requires a lot of labor for the staff; 2. Because multiple tests are required to ensure test accuracy, staff manually change samples, resulting in low test efficiency; 3.
