Abstract
The formation of composite materials is disclosed, using high energy rotary impact milling. The illustrations utilize polymer resin particles as the matrix material, and solid particle fillers. Ultra-small particle sizes are used for both the matrix and filler materials. When the resultant materials are processed by usual forming techniques, the resultant composite materials possess strength properties approximately equivalent to those of the unfilled matrix material, even though heavily filled.
