The mechanical properties of tubular braided structures influence their inherent performance during application as biomedical materials. In their use as stents, braided structures are forced to conform to the topology of the host tissues. Triaxial braided structures have had limited use in tissue repair and organ support even though they have the potential of offering equal if not better performance compared to bi-axial braided structures. A study of the mechanical dynamics of tri-axial braids would be crucial in the potential design of customised structures for advanced tissue repair and organ support. This study therefore uses Finite Element Methods (FEM) to design and develop triaxial braided structures and investigate their crimping behaviour using parametric modeling and numerical analysis in their potential application as biomedical materials. The results in this study portrayed that the presence of axial yarns in tubular braided structure offers improved performance in terms of stability of the structure.

三轴编织结构卷曲行为的数值分析

管状编织结构的机械性能影响其在作为生物医学材料的应用过程中的固有性能。在用作支架时,编织结构被迫符合宿主组织的拓扑结构。三轴编织结构在组织修复和器官支持方面的应用有限,尽管与双轴编织结构相比,它们有可能提供同等甚至更好的性能。三轴编织物的机械动力学研究对于高级组织修复和器官支持的定制结构的潜在设计至关重要。因此,本研究使用有限元方法 (FEM) 来设计和开发三轴编织结构,并使用参数化建模和数值分析研究其压接行为在其作为生物医学材料的潜在应用中。本研究的结果表明,管状编织结构中轴向纱线的存在提供了结构稳定性方面的改进性能。
