COMPOSITE ABRASIVE FILAMENTS, METHODS OF MAKING SAME, ARTICLES INCORPORATING SAME

摘要

2128092 9318890 PCTABS00025 A composite abrasive filament, including at least one preformed core at least partially coated with a hardened, abrasive-filled thermoplastic elastomer, exhibits increased abrading life over previously known abrasive filaments. Previously known abrasive-filled nylon filaments have limited stiffness and lose their stiffness as temperature approaches 70 ·C. The composite abrasive filaments of the present invention are more efficient and more resistant to flex fatigue failure than abrasive-filled nylon filaments. Also disclosed are methods of making such filaments and using such filaments in article form to abrade a variety of workpieces.
