| 摘要 |
Reinforcing material which does not have a melting point which is compatible with the processing temperature of an elastomer can be incorporated into the elastomer in the form of melt blown fibers. In the method of the invention, melt blown fibers are made by melting a reinforcing material in an extruder, and extruding the reinforcing material through a die comprising many small holes, while simultaneously blowing air or nitrogen, under high pressure, through the die holes, and collecting the resulting material on rotating rolls. The fibers thus formed are mixed into an elastomer using conventional mixing means. A composite made by the method is also provided.
