"Skeleton construction" 2.0

Carbon fiber reinforced plastics (CFRP) possess a huge potential in lightweight construction terms. Thanks to the integrated carbon fibers, CFRP can absorb enormous tensile forces when compared to metals for example, or non-reinforced plastics. The weight specific benefits of CFRP are best exploited when the carbon fibers in the material mix are laid out in a "loadpath compliant" way, which in turn is a precondition for a load oriented design of the material.
Based on very promising results from the project MAI Skelett, MAI Multiskelett is focused on the further development of the skeleton construction. Process technology solutions should be created for the crossing area of bearing components, profiles and for high load introduction areas, particularly for large structural components where several main loadpaths cross, so that the skeleton construction method can be transferred to more complex components with multi-axle requirements. To this end, a process chain should be created which will be sufficient to cover everything from the design to the construction component production and right up to the long term cost efficient large series production.

The MAI Multiskelett application provides for the creation of process technology solutions which will contribute an essential part towards the future production of cost efficient thermo plastic CFRP manufacturing processes and are therefore an important contribution to the aims of the BMBF leading edge cluster MAI Carbon. Among others, these are the reduction of production costs and cycle times, material cost reduction and the build-up of innovative CFRP production technologies and process chains.
