A low-wear fluoropolymer composite body comprises at least one fluoropolymer and additive particles dispersed therein. Also provided is a process for the fabrication of such a fluoropolymer composite body. The composite body exhibits a low wear rate for sliding motion against a hard counterface, and may be formulated with either melt-processible or non-melt-processible fluoropolymers.
