COMPOSITE MATERIAL WITH PARTICLES OF MECHANICALLY RESISTANT MATERIAL

摘要

Composite materials are disclosed which consist of an elastomer matrix, especially rubber based, and embedded rounded, edge-free particles of mechanically resistant material coated with an adhesive. The materials exhibit a great wear resistance and good anti-skid properties or smooth surfaces. They are especially suitable for use in the treads of vehicle tires. A process is also disclosed for the production of rounded, edge-free and pressure-resistant particles of mechanically resistant material by mechanical treatment of initial particles of any shape.
