A composite material having superior tribological properties includes a
first polymer being a transfer film forming polymer and a second polymer
mixed with the first polymer. The first polymer is at least 10 weight %
of the composite and the composite provides a wear rate of <10.sup.-7
mm.sup.3/Nm and an average friction coefficient of said composite no more
than 0.15. The first polymer can be PTFE and the second polymer a
polyaryletherketone (e.g., PEEK). A method of forming composites includes
the steps of providing a plurality of transfer film forming polymer
particles and second polymer particles, and molding or extruding the
particles at a temperature sufficient to allow softening and mobilization
of at least one of the transfer film forming polymer particles and the
plurality of strengthening phase polymer particles to form an
interconnected network, wherein the composite formed provides a wear rate
of <10.sup.-7 mm.sup.3/Nm.
