Material simulation was crucial to material performance. Tribological behavior and thermal stability of polytetrafluoroethylene (PTFE) composites was well known to be affected by factors depending mainly by matrix and filler properties. However, the mechanism taking place had not still been fully explained. In this work, the composite material filled with different ratio PSA fiber and siloxane had been investigated using scanning electron microscope, electronic universal testing machine, shore durometer and friction–abrasion testing machine, and the material was simulated. The result showed that the tensile strength and hardness of the composites were improved due to good dispersion of PSA fiber in the matrix and the good interface with the matrix when the lower content of PSA fibers. Tribological properties of composites and dual surface transfer films of PTFE/ PSA composites were improved by PSA fibers and silane coupling agent were used cooperatively. Cone calorimeter test and thermo-gravimetric analysis indicate that 4$$^{\# }$$# sample had lower heat release rate, mass loss rate. The 4$$^{\# }$$# sample had been endowed with the better thermal stability due to the hybridization of silane and PSA. This laid a foundation for further simulation analysis research and application of the composites.
