Mechanical Properties of 2D Braided Polyester Ropes

The relationship between the structure parameters and the mechanical properties of two-dimensional braided polyester ropes were studied. 22 times of polyester ropes were braided with different pitch length and different yarns, and their tensile properties were tested, then the relationship between the mechanical properties of the rope and braiding pitch was obtained. The results showed that the breaking strength of 2D braided ropes increased with the increase of pitch length, but after achieving certain length, the strength began to decline, and the breaking elongation decreased along with the increase of unit length.
