Composites made of high performance textile materials are known for their overwhelming mechanical properties and compelling lightweight character. As load optimized design of the reinforcement structure is the key to prosperous lightweight composites, the attention is on the design of anisotropic and inhomogeneous reinforcements, which is both challenging and promising. Nevertheless, the development of complex textile preforms, as well as the realization of the preforming process, is currently cost and time intensive. Since the modern lightweight industry is heading towards full automatization and absolute flexibility, the motivation for a simulative prediction of composite properties is on the agenda. The overall digitalization of design, development and fabrication holds great possibilities for the composite market. Therefore, a completely virtual development chain for fiber reinforced composites is introduced in this paper. A method for modelling composite reinforcements on a micro-scale level in function of the manufacturing parameters is established. The introduced micro-scale models are able to predict both, the dry textiles mechanical properties and the mechanical properties of the composite materials. With this approach, virtual drape simulations for the optimization of the preforming process and simulations of the load bearing capability of the composite parts are enabled.
