Abstract
A composite material for enhancing traction between a surface of an article made of the material and a second contact surface is disclosed. Fine chips are encapsulated in covering material to form covered particles. The covered particles are evenly dispersed within a base material. The covering material is harder than the base material; the second contact surface material is harder than the covering material; and the fine chips are made from a material that is harder than the second contact surface material. As the surface of the article made of the material and the second contact surface interact, the fine chips are continuously exposed to the second contact surface. As a result, the fine chips are free to engage small indentations in the second contact surface and to bite into ice on the second contact surface, if any ice is present.
