Composite materials that include fluoropolymers. Methods of reducing friction, which may include contacting a first article and a second article that include or are formed of one or more fluoropolymers. The composite materials may include a fluorinated polymer and a first filler. The first filler may be present at an amount of about 3% to about 50%, by weight, based on the total weight of the first fluorinated polymer and the first filler.
