Tailored Thermosets & Biomaterials

The competence field Tailored Thermosets & Biomaterials has an interdisciplinary focus on energy, mobility and eco-efficiency. Core element is the development of reactive multifuncional composites in the context of environmentally benign manufacturing processes and tailor-made properties. The focus is on the development of an innovative modular building block system as a bottom-up technology platform, with new materials, preferably from sustainable raw materials, as well as functional fillers and reinforcing materials. Substances with interaction between matrix and particles as well as the use of functional principles from nature are of particular interest. Competencies in physical,chemical and especially fracture mechanics methods are constantly evolving.

Focal points are the elucidation of structures and properties on a micro/nano scale as well as the failure behavior (fatigue crack propagation, environmental stress cracking formation). New measurement methods, such as Temperature-Modulated Optical Refractometry (TMOR), are used. Thus, our aimis to develop innovative materials from the fundamental understanding of morphologies, mechanisms and correlating models.
