Claims
- 1. A method for the manufacture of a nylon shape that incorporates a particulate filler and in which the filler particles are not fully wet out by the nylon but instead are held in small clusters within the nylon matrix, the improvement comprising:
- melt mixing at least 90 percent by weight of nylon with less than 10 percent by weight of a heat-reactive polyimide,
- partially curing the polyimide to form an easily ground composite,
- grinding the composite into a molding powder,
- mechanically mixing the particulate filler with the molding powder,
- melt forming the nylon shape from the mechanical mixture, and
- completing the cure of the heat-reactive polyimide.
- 2. A method according to claim 1 wherein the particulate fillers are selected from the group consisting of solid lubricants and conductive particles.
- 3. A method according to claim 2 wherein the filler is a solid lubricant selected from the class consisting of molybdenum disulfide and boron nitride.
