Abstract: Composite materials are prepared by mixing metal powder and dissimilar reinforcement materials in a fluid binder to form a slurry. The slurry is spread to form thin sheets which are air dried. The sheets are stacked to a predetermined thickness and placed in a vacuum retort where binder is removed at elevated temperature and reduced pressure. The resulting composite material is consolidated and bonded at elevated temperature and pressure.
