Specially designed hybrid materials can be used as a model system to compare its properties and structural design principles with those of biological materials such as bone. We aim to develop new combinations of multi scale analytic tools, to investigate the correlation between macroscopic material mechanics and microscopic structure of bioinspired hybrid materials. To understand deformation processes in two model systems, X-ray scattering techniques and tensile testing experiments were combined in a specially designed apparatus. The first model system is a composite material, composed of submicron metal fluoride particles embedded in a poly(ethylene oxide) matrix. First results allow us to follow crystal orientation effects during tensile testing, indicating a reorientation of crystalline domains in the material. The second model system is based on natural collagen extracted from turkey leg tendons as organic part infiltrated with different metals. We investigated the usability of these tendons as matrices for metal infiltration and compared untreated collagen with metal-infiltrated collagen. First results lead us to the assumption of a directional embedding of the metals into the collagen structure.
