Composite Properties

The present contribution aims to investigate the ability of drawing predictive conclusions from homogenization in case of damage. Therefor, two topics will be addressed. On the one hand, material properties for the constituents on the microscale have to be derived, to render a predictive homogenization possible. The investigation at hand is concerned with glass fiber reinforced epoxy resin. In this example the properties of the fiber and the matrix have to be studied individually by experiments. Furthermore, the interface between both materials needs to be examined. To this end experiments on several models of single fiber composites have been developed in the literature. For the present material combination single fiber fragmentation tests and pullout tests have been conducted and evaluated. On the other hand, boundary conditions are necessary, that allow for the strain localization in a volume element without leading to spurious localization zones.
