Inverstigation of tensile and tearing behaviours of laminated car seat fabrics

In this study, the tensile and tear strength of laminated fabric used as an automotive seat cover was simulated using finite element analysis. The laminated fabric has three layers and is composed of plain weave fabric and twill 2/2 at different densities, PU foam, and PA circular knitted scrim. FEA simulation was carried out on the constructed fabric geometrically using the 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 and tearing strength results of the simulations agree well with the actuals 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. This study is the project of San-Tez that has been numbered 1001.STZ.2015 and named "Deformation Analysis with Finite Element Analysis (FEA) of Automotive Woven Fabric as a Seat Cover Form". All experimental studies were in the facilities of Martur Sünger ve Koltuk Tesisleri Ticaret ve Sanayi A.Ş.
