In this contribution, the composites with textile reinforcement and rubber matrix are studied experimentally and computationally together. The reinforcement is in the form of fibre. These composite are applied in tyres for cars, conveyor belts etc. The aim of research work of authors is creation of computational models namely for stress-strain analyses of selected parts of radial tyre casing for passenger cars. The typically radial tyre casing consists of one or two layers of polyester in tyre carcass and two layers of steel-cord belt and one layer of polyamide belt in tread area. The FEM program ANSYS was used for computational modelling. For the determination of the material parameters of rubbers and textile reinforcement as input data to computational models, it was necessary to perform experiments such as statically tensile tests. Also the experiments of composites such as statically tensile and bend tests and namely cyclic loading tests are needed to verification analyses between computational results and experimental data. The material parameters as module elasticity and Poisson ratio describe of the textile fibre. The results from the computational modelling of strain-stress states and selected results from the experimental tests are presented in this contribution.
