Considering influence of microstructure morphology of epoxy/glass composite on its behavior under deformation conditions-digital material representation case study

Digital Material Representation (DMR) concept in application to numerical investigation of the two different types of epoxy/glass composite morphologies under loading conditions is addressed within the paper. First, two algorithms for reconstruction of digital microstructures based on metallography investigations are developed. Then, material properties of the investigated epoxy matrix and glass fillers are evaluated based on an in-situ tensile test as well as nano-indentation, respectively. At this stage a numerical investigation is also extended by series of experimental tensile tests to understand basic mechanisms occurring during deformation of the two different types of glass particles fillers. Finally, an example of practical application of the developed digital microstructure model for multi scale calculations of the epoxy/glass composite under loading is presented.
