ABSTRACT:
A method and system for producing a continuous supply of low volume fraction composite material that can be fed continuously into one or more molds. Composite inputs are fed into a mixing device such that a continuous supply of mixed composite material is available from the output side of the mixing device. The operation removes the step of creating master ingots and removes the need for a two step process in which the material is melted twice. This invention reduces the cost of producing composite components, reduces batch-to-batch variations, and allows for a continuous production flow. In addition, the invention allows for a much greater flexibility in the selection and optimization of material systems.
