Abstract in different language:	This work focuses on the multiscale modeling of composites made of layers consisting of hybrid fabric reinforcement and polymer matrix. The fabric (HP-P167AC) is a plain-weave textile with carbon (3K, 200 tex) and aramid (Kevlar 49, 158 tex) tows each placed in single direction only. The matrix is made of thermoplastic foil Polyvinyl butyral (PVB). The composite material is made in form of a plate by hand lamination of 10 layers of fabric having the same orientation and 20 layers of PVB using autoclave technology with vacuum bagging. The goal is to create a numerical FEA model that can be used for the prediction of mechanical behavior including strength prediction on the macroscale. The material has orthotropic properties caused by the hybrid nature of each layer since the carbon and aramid fibers have different properties and, moreover, the tows have different geometry and spacing.
