Material Cycles

The Material Cycles competence field deals with issues surrounding the optimal use of materials in terms of a closed carbon cycle. The optimal use of renewable raw materials, such as natural fibers or fillers, is examined as well as the use of chemicals and polymers from renewable sources. Here, thermal resistance and surface properties for the best possible fiber-matrix bonding and high-performance use are key issues. Naturally occurring structural properties of natural fibers, when used in a targeted manner, can add value through additional functionality.

Understanding this fundamentally is the subject of research in the competence field. In addition, the recycling of materials and components made from composite materials, with a focus on carbon fibers, is an important aspect in the optimal use of raw materials and thus part of the competence field activities.
