High-Performance Production of CFRP Structures

Hochleistungsproduktion von CFK StrukturenAs an inter-university research group, we have set the goal for ourselves to develop a comprehensive solution for the economical and reliable production of carbon-fiber-reinforced-plastic (CFRP) components in aviation industry. With this we are aiming for manufacturing properties that meet the requirements of a larg-scale part production of this industry.

Alongside the closed process chain, we set the following sub-targets in our areas of expertise:

In the area of construction methods and structures, more efficient light-weight construction concepts are developd based on and in interaction with materials and process sequences. We are concentrating on robust and reliable manufacturing geometries, taking into account the structural mechanical effectiveness of these parts. The optimization of the construction method includes global, local and tolerance-related parameters.

When it comes to materials, processes and process chains of CFRP component manufacturing, the challenges of future structres must be countered. Especially with regard to high process spees, an increased robustness and effective performance of the system components. Therefore, we are developing new solutions for the material systems; textiles and resins with respect to a process suitable for serial production.

In order to achieve a high-performance production of CFRP structures, a comprehensive plant and process automation is also a prerequiste. We consider draping and tooling systems with a high form-flexibility, which provide both solution approaches to overcome tolerance problems during production as well as high flexibility in the shape design. Process integrated quality monitoring systems also support the high level of automation.

In order to guarantee an economical CFRP production, the entire project is to be accompanied by a cost-effectiveness analysis, taking into accout interactions within the process chain. This is done in addition to the fundamental research of the partial objectives mentioned above.

In addition to these scientific objectives, a didactic objective is pursued with the project. This enables the next generation of scientists to prepare their dissertation in a structured and targeted manner within the institutionalized project group. This includes integrating compentences relevant for the labor market into the doctoral education, such as professional-methodological and social-communicative skills. This increase the employability of the scientific staff. Application-oriented interships as well as industrial research cooperations also help young academics to network with the regional economy and thus strengthen the recognition of the universities involved.
