The twist of the suture is an important parameter that affects the suture effect. If the suture is not twisted, the suture is easy to wear and fluff during the sewing process, resulting in thread breakage. At the same time, that will affect the suture effect and the strength of the suture itself. The article uses experiments and simulations to compare the mechanical properties of carbon fiber twisted threads. Refer to GB/T 3362—"Test Method for Tensile Properties of Carbon Fiber Multifilament" to test the tensile strength of T700-12K carbon fiber tow. And in ABAQUS, the three-dimensional Hashin damage criterion is used for 20 twists/m, 50 The carbon fiber sewing thread with twists/m and 80 twists/m is subjected to finite element prediction. The results show that the carbon fiber sewing thread with 80 twists/m has higher tensile strength than the carbon fiber sewing thread with 20 twists/m and 50 twists/m.
