Test Background
The puncture resistance of coated fabrics refers to the ability of coated fabrics to withstand penetration by sharp objects from the outside. Puncture resistance test of coated fabrics Applicable to coated fabrics coated with rubber or plastic on one or both sides.
Zhongke Testing Environmental Reliability Experiment Center has the capabilities of environmental testing and reliability performance testing of various rubber or plastic coated fabric materials and products, and provides professional puncture resistance testing services for coated fabrics.
Test Principle
Use a thorn cone to vertically pierce the circular sample clamped on the ring clamp at a constant speed, and record the force required to pierce the coated fabric.
Test method
1. Clamp the sample in the ring clamp, with the surface to be measured facing the thorn cone.
2. Connect the thorn cone and ring clamp to the upper and lower holders of the testing machine respectively to ensure that the thorn cone is perpendicular to the surface of the sample. The length direction of the flat end of the thorn cone is 45°, 90° or 180° with the longitudinal direction of the specimen.
3. Adjust the speed of the testing machine to (500±50) mm/min or (300±15) mm/min, with (500±50) mm/min being preferred.
4. Start the testing machine and record the maximum force value when the thorn cone completely penetrates the coated fabric.
