Tensile fracture test and constant load tensile fatigue test were carried out on three different types of mesh fabrics, including knotted netting, warp-knitted knotless netting and braided knotless netting, to compare and analyze the mechanical properties of mesh fabrics produced by different processes. The results show that the tensile fracture of all three fabrics occurs at the connection between netting knots and legs, which is more likely to cause stress concentration. In the tensile fracture test: braided knotless netting has the highest fracture tensile, followed by knotted netting and warp-knitted knotless netting; warp-knitted knotless netting has the highest rate of increase in knot strength, followed by braided knotless netting and knotted netting; the descending order of break elongation is warp-knitted knotless netting, braided knotless netting and knotted netting, indicating that warp-knitted knotless netting has the best elongation. In the tensile fatigue test, the warp-knitted knotless netting has the highest irrecoverable strain energy coefficient, the highest energy consumption and the worst fatigue resistance, while the fatigue resistance of braided knotless netting and knotted netting is better. The study results can provide a basis for users to choose the right type of mesh fabrics. [ABSTRACT FROM AUTHOR] |
