Abstract: As interest in braiding as a method of composite reinforcement grows, it becomes important to understand the drapability of braided sleevings. This work aims to deepen this understanding by creating an analytical model to determine the minimum achievable bend radius of a biaxial braided sleeving on a flexible mandrel. The model predicts the change in braid structure from applied deformation and the resulting elastic strain energy. An experiment was done to validate the model and determine the strain energy at which bending can no longer continue. While specific to a supported, multi-layer biaxial braid in bending, the principles behind the model can be applied to other fabric architectures and loading applications.
