Abstract
A filled resin composition is provided which is particularly adapted for the formation of wear-resistant, lubricious surfaces. The compositions when formed into integral threads with the bodies of plastic-reinforced pipe provide superior thread action and extended thread life. The compositions comprise a thermosetting resin such as epoxy resin and hardener, in combination with a filler which in turn comprises ceramic powder, graphite and short fiber lengths. The compositions may vary widely as will hereinafter become apparent.
Claims5
A wear resistant, lubricious composition particularly adapted for use as a wear-resistant surfacing and particularly adapted for use as a matrix for fiber-reinforced bodies comprising about twenty to eighty percent by weight epoxy resin and hardener and about twenty to eighty percent by weight of filler;
- said filler consisting essentially of ceramic powder in a weight percentage of about eighty-eight to ninety-nine and one-half percent by weight of said filler, and graphite powder in a weight percentage of about one-half to twelve percent by weight of said filler.
A curable, thread-forming composition consisting essentially of about eighty to twenty percent by weight of thermosetting resin and hardener therefor, and about twenty to eighty percent by weight of filler;
- said filler consisting essentially of ceramic powder and powdered graphite;
- said graphite being present in the amount of about one-half to ten percent by weight of said filler.
