Formation of thermally induced crack patterns in anisotropic, fiber-reinforced composites with a brittle matrix
Project description: The subject of this research is the characteristic thermal-induced crack patterns in anisotropic fiber-reinforced composites with brittle matrix. The investigation of the crack pattern formation is carried out both directly in experiments and indirectly, mechanism-oriented with the aid of simulation studies based on the phase field method. The focus is on the investigation of mechanisms for crack pattern formation during hardening/tempering or pyrolysis in a purely mechanical-elastic description. The central element of this description is the different shrinkage behavior of fibers and matrix during the thermal treatment.
