Scope

Main technical content: 6.1 Cut two rectangular samples with dimensions of 100±1mm × 75±1mm from the steel cord fabric and nylon fabric. 6.2 Accurately align the nylon fabric with the two steel cord fabric samples. Align the cellophane paper along the edge of the steel cord fabric sample that does not have the nylon fabric attached, to create half-samples A and B. Then accurately align the half-samples A and B together and press them evenly with a flat pressing roller. 6.3 Follow the method specified in Chapter 8 of GB/T 6038-2006 to place the samples flat in a mold. Under the conditions of 150°C temperature and 1.5MPa pressure, vulcanize the samples for 23 minutes. After vulcanization, let the samples rest for at least 10 hours. 6.4 Use a knife to cut out 3–5 small samples with dimensions of 25mm±1mm from the samples. 6.5 Follow the method specified in Chapter 9 of GB/T 15254-2014 to set the tensile speed of the tensile tester to 100mm/min, stop at about 5mm from the end of the sample, and ensure that the sample is not completely stretched apart.
