The study focuses on the realization and validation of a suitable concept for composite fuselage frames which play a crucial role in aircraft structures. The frames developed within this work cover geometry design, sizing, material selection and manufacturing concepts. C-frame concept was chosen due to several reasons, e.g. simple geometry, good interface capability and high integration potential. The highly integrated braided frames without clips (fastener free) manufactured via braided preforms and resin infusion were aimed to reach a total weight reduction of more than 10 %, whereas part stiffness could be better. Developments were conducted to improve the quality of preforms and to identify the key process parameters which mainly influence the quality of the infused products.
