Composite materials are crucial in current component development to improve the functionality and lightweight design. No longer limited to the aerospace industry, they are widely used in civil aviation, transportation, construction, and engineering.
Assessing the material behavior of composites (e.g. fracture behaviour) by experimental determination is highly complex due to their inhomogeneity and the interplay of anisotropy and differences in stiffness of the single material components.
Also difficult is determining the permeability tensor of the non-infiltrated laminate, required to perform an adequate mold-fill simulation and ensure a complete infiltration of the component, and the permeability changes with each modification of the stacking sequence of the laminate.
Through computer simulations, new composite materials are engineered by honing in on a few promising designs and restricting costly lab tests to these few designs.
GeoDict for Composites
The digital revolution for composites
The digital material laboratory software GeoDict is an integrated and user-friendly unique solution for the design of composites.
GeoDict models the composites’ microstructure from material samples scanned by microCT and FIB/SEM, or creates new microstructure models from user-defined parameters.
GeoDict analyzes the geometric shape of the reinforcement, e.g. fiber orientation, fiber volume fraction, fiber diameter distribution, or fiber curvature.
The composite's macroscopic material properties are computed on the microstructure model using fast solvers for structural mechanic, fluid flow or conductivity simulations.

GeoDict package for Composites
Accurate numerical material simulations performed with GeoDict provide useful insights into the composites’ microstructure which traditional experiments cannot give and, consequently, accelerates and cuts down cost in the development process.
