Abstract
In this study, aspect ratio and major axis of fiber bundle cross‐section of braiding yarns, and gap between braiding yarns obtained from cross‐sectional observation were approximated as a function of distance between braiding yarns. And the prediction method of interrelationship between internal structures for designing braided composites was proposed. In addition, the prediction method were utilized to predict thickness of layered braided fabrics considering nesting of each layers for designing stiffness of braided composite structure.
