CFRP components at their limits

In the MAI Hiras + Handle project, research will be conducted into the limits of carbon fiber composite systems and how far these depend on the fiber length. The project will also investigate how overlapping different fiber systems can affect their performance and the properties of components.

An important point within the project is the develop-ment of an appropriate simulation method for three-dimensional components as part of the vehicle structure. In that respect, the effects of both the three-dimensionally deformed components and the carbon fiber reinforced material must be taken into account. The project work also includes upgrading automation with a matching gripper solution and optical fault detection. As a result, a largely automated process will be created as early as in the research stage. This process will take into account the requirements to be applied later on in series application.

All results of the MAI Hiras + Handle project will be incorporated into the component demonstrator, which will be tested under real experimental conditions. All the requirements of the project must be considered and implemented in this (component under permanent dynamic load, not crash-relevant, overlapping of different carbon fiber lengths, cost-effective manufacturing processes suitable for high-volume production).

The expected findings are intended to minimize the risk in order to allow cost-effective mass production of CFRP structural components in the automotive industry in future.
