Abstract
Abstract A composite material is formed of a carrier having a cellular structure and diamonds or other hard, abrasive particles received within the cellular structure. A matrix material holds the diamonds in the carrier, and the matrix material may be the carrier itself or an additional substance such as a metal powder or resin. The diamonds may protrude from the composite material for aggressive working, or may be embedded for longer life of the material. The cellular carrier has a skeleton that protects and mechanically supports the diamonds within the composite material for greater durability of the composite material.
