The material properties desired for grinding or cutting tools are a combination of strength and high hardness to overcome the high strain abrasion from the constant movement against the rock under high load, and very high toughness to survive the impact of the material as it is loaded and unloaded. In an effort to improve the damage resistance of wear materials, fibrous monolith (FM) materials have been investigated in which the microstructure is organized into repeating regions of hard, wear resistant materials surrounded by a layer of ductile material. In this way low wear rates can be achieved. In the present paper, the hexagonal cell and cell wall phases have been modeled using the micro-mechanical model DENDRO. The elastic response of the FM architecture is predicted for a variety of loading conditions. The model will establish fracture resistance for a variety of materials combinations and FM architectures.
