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.

Purpose The purpose of this paper is to study the ablative behavior of the silicone resin-coated carbon fabric (coated fabric) that will swell significantly during ablation. Design/methodology/approach The ablation experiments of three coated fabrics were conducted by quartz lamp radiant. Based on the experimental analysis, a numerical model was proposed for the coated fabrics to study the ablative process in term of the energy balance, mass conservation and thermal decomposition equations. Findings Results showed that the average relative errors between the simulated temperatures and experimental values of back surfaces of coated fabric 1, 2 and 3 were 10.01, 7.53 and 7.32%, respectively. The average density of silicone resin of coated fabric 1 was reduced by 47.96%, and the closer the distance from the heated surface was, the more the density decreased. The thermal conductivity and specific heat capacity of silicone resin of coated fabric 1 increased with time. Before 50 s, each decomposition rate curve showed an inflection point, at which the silicone resin decomposed most intensely. Research limitations/implications Based on experimental observations, the ablative behavior of the material with fixed expansion layer was simulated. In the further research, the moving expansion layer could be considered. Originality/value This paper provides the theoretical basis to evaluate the effectiveness of thermal protection materials that will swell during ablation.

This paper proposes an effective method to predict the thermal conductivity of plain woven blended fabric to optimize woven fabric structure, and to evaluate thermal comfort. The unit cell model of fabric is established for numerical simulation of heat transfer through thickness. The thermal conductivity of blended yarns is calculated by a series model. The temperature and heat flux distributions are verified experimentally.
