“Skeleton structure” saves weight
Carbon fiber reinforced plastics (CRFP) have a high potential for lightweight construction. Compared to metals or unreinforced plastics, the CRFP can absorb enormous tractive forces due to the integrated carbon fibers. The weight-specific advantages of CFRP are best used when the carbon fibers are aligned along a suitable path in the matrix material, which requires a load-oriented construction of the material. However, this has only partially been implemented in the automotive industry. This is where the project MAI Skelett starts. The project aims to develop a new manufacturing process to produce CFRP components in a skeleton construction where the construction has to be illustrated using a so-called roof bow (a component in automobiles). A process chain has to be developed which extends from the construction to component manufacturing and allows for cheaper large-scale production.

The technical solutions, which have to be developed by the MAI Skelett project, will make an essential contribution to providing cost-effective thermoplastic CFRP production processes in the future and are therefore an essential part of the objectives of the BMBF Leading-Edge Cluster MAI Carbon. These include the reduction of production costs and cycle time, reduction of material costs and the development of innovative CFRP production technology and process chains.
