Abstract
A PTFE-based composite material includes a PTFE major phase filled with a metal oxide minor phase. The major phase is intermixed with the metal oxide minor phase, wherein the minor phase includes a plurality of irregularly shaped metal oxide nanoparticles. The irregularly shaped nanoparticles provide substantial reductions in steady state wear rate over otherwise similar nanocomposites. The metal oxide can comprise aluminum oxide.
