[0002] As a reinforcing substrate, glass fiber mesh is widely used in building exterior wall insulation systems, concrete reinforcement and industrial anti-corrosion fields. Its tensile strength, weather resistance and corrosion resistance directly determine the safety and durability of engineering structures.

[0003] In the production process of glass fiber mesh cloth, various tests are required, among which the tensile breaking strength test is crucial. According to the requirements of standard GB / T7689.5-2001 "Determination of tensile breaking strength and breaking elongation of glass fiber", glass fiber mesh cloth needs to be tested multiple times to ensure the accuracy and reliability of the test data.
