Although the great potential of carbon fibers for use in lightweight applications has been demonstrated
in the past, their cost and environmental impact remain a barrier to their widespread use [1]. Recycling
of carbon fibers from end-of-life components and combining them with thermoplastic fibers to form
hybrid yarns addresses both issues. Due to the stochastic nature of hybrid yarns in terms of recycled
carbon fiber (rCF) length and orientation [2], their influence on drapability and performance of rCF
composites needs to be investigated. In this paper, a micromechanical model for analysing the dry and
composite properties of yarns made from rCF is presented. By using a self-developed framework for
generating representative volume elements (RVE) based on parameters such as fiber length, orientation,
waviness, and fiber volume content, a variety of idealised random yarn geometries is created. A
subsequent simulation step of the compaction of the RVE assures a more realistic RVE geometry. The
models are validated by carrying out virtual tests and comparing the results with real tensile tests. The
modelling approach can be used for further analyses.
