Hybrid polymer based materials

Modern components for use e.g. in mobility, energy, or building and construction have to fulfill increasing requirements regarding their performance characteristics, energy efficiency, and sustainability. Hybrid components are the solution frequently, as they show outstanding performances very often.

The boundaries between different material classes thereby may be overcome. What counts is the combination: the combination of materials on different scales from Nano to Macro and the combination of different technologies for production purposes, i.e. the development and utilization of hybrid processes for manufacturing hybrid structures from hybrid materials.

At the first glance metals seem to be the ideal materials for lightweight design because of their high stiffness. However, when it comes to lightweight applications we rather need to talk about the unit weight based properties. When referring the elasticity modulus of different material classes to their respective density, hybrid materials e.g. fiber reinforced plastic composites are unequaled regarding their performance.

Hybrid materials on different length scales provide an extremely broad property range not being covered by any single material class. Because of the excellent stiffness to weight ratio of microscale reinforced plastics and potential effects on the morphology scale of the polymeric matrix of nanocomposites hybrid materials are the ideal material for lightweight applications.

To exploit the enormous market potential of hybrid materials we pivotally need to optimize morphology generation during component part manufacturing by cost-efficient hybrid processes.
