The ability of multidirectionally X-D braided composites to contain damage is one of the major advantages offered by this material. This report describes the development of analytical methods for determining the fiber geometry, stiffness, and impact damage response of X-D braided composites. The fiber geometry model is based on the braid parameters used in the construction of X-D braided composites. The stiffness model is based on this fiber geometry model and laminated plate theory. The impact damage model is based on the braided fiber geometry and the fracture toughness of the resin system used in the X-D composite. This report also describes the results of experimental studies conducted to evaluate the results of the theoretical models.
