Finite element analysis of the tensile strength of laminated fabric for automotive seat covers

Abstract

In this study, the tensile strength of laminated fabric used as an automotive seat cover was simulated using finite element analysis (FEA). The laminated fabric has three layers and is composed of plain weave fabric and twill 2/2 at different densities, polyurethane foam, and polyamide circular knitted scrim. FEA simulation was carried out on the constructed fabric geometrically using KTEX software. The laminated fabrics were then subjected to axial stress with opposing forces. The laminated fabric is assumed to be linear and elastic in FEA. The simulation outputs were compared with real test results and their graphs. The geometrical construction of laminated fabrics is crucial to obtain beneficial results. The tensile strength results of the simulations agree well with the actual values, although the strain-stress graphs may differ in several zones. The consistency between the actual test results and simulation may provide a model for surface deformation for further studies.
