The invention relates to a self-lubricating composite friction part (1) that can be subjected, during operation, to temperatures that are at least equal to 250°C. Said part comprises, along the friction surface (2), a single layer of a material consisting of weft and warp yarns made of polytetrafluoroethylene, said material being impregnated with a thermostable resin having a glass transition temperature that is at least equal to 250°C. It is applied to a reinforcing layer (3). |
