Elastic properties of large‐open‐mesh 2D braided composites: Model predictions and initial experimental findings

Conventional applications of two‐dimensional tubular braided composites mostly require closed‐mesh braiding; however, some stiffness‐critical applications may require use of open‐mesh braiding. Most likely candidates for the open‐mesh braided composites are in the medical field, such as braided catheters and stents. Analytical and experimental investigation of the open‐mesh braided tubular composites is very limited in the open literature; therefore, this study is an initial attempt to close this gap. The article investigates elastic properties of the open‐mesh braided composites (e.g., braided catheters) and open‐mesh composites with holes (i.e., stent‐like structures). Analytical results are also compared with that of experimental results. Findings may be used in design of braided medical tubular composites. POLYM. COMPOS., 31:2017–2024, 2010.
