Utilization of polycomponent composites in automobile transport

Abstract

Polycomponent composite materials for automobile transport are used in interior of automobiles and namely for tyre manufacturing. The tyres are essential elements into interactions between vehicles and roads which secured of force transmission with ability of damping of road irregularity etc. Therefore it expect from these materials with theirs excellent material parameters that will be able to good securing of observance of right function with respect to working requirements of automobile and high tyre life. The contribution deals with complex composite – tyre for its characteristic specific deformation properties. These properties are determined of construction – geometry and placement of reinforcements and also tyre materials. The computational modelling of strain-stress states of selected composite assisting to solution of right selection of optimum geometry and placing reinforcing long-filaments – cords. The authors used for computational modelling the Finite Element Method program ANSYS. The orientation is namely on materials parameters of rubber matrix and steel-cord reinforcement, which are applied into tyre casing for passenger vehicles. It is necessary to deal with materials for tyre manufacturing and also materials upon degradation action with respect to transport safety.
