Abstract
The Institute for Aircraft Design (IFB) examined a Non Braided Zero Degree (NOBRAZED) configuration in 2008. A specific number of NOBRAZED fibers can be integrated into the preform between two biaxial layers. A certain number of axial fibers, eight in the transmission shaft project, are offered underneath a standard braiding machine in the NOBRAZED configuration. The braiding fibers show considerably more undulations due to the third fiber system in a triaxial braiding configuration. The characteristic mechanical properties of the triaxial braid were the motivation for the NOBRAZED configuration. All tested transmission shafts were 925.78 mm in length and 26.0 mm in inner diameter. The shafts were braided with three layers on a steel mandrel. A broad test campaign shows that the braiding configuration has a considerable influence on both torsional performance and damage tolerance. The CT scanner investigation showed that the NOBRAZED fibers operate like a separator during the impact.
