Abstract:
1. A method of preparing composite materials, comprising the steps of: placing particulates and an adhering material in a rotary body having a planar bottom surface, a side wall extending from said bottom surface, and an inwardly extending flange at an end of the side wall away from the bottom surface, the flange leaving through which the particulates can be fed into the rotary body; rotating said rotary body so as to apply centrifugal forces of about 2G or more to said particulates in said rotary body; while the centrifugal forces are applied to said particulates, varying the inclination of said rotary body from an arbitrary inclination angle at which said bottom surface of said rotary body forms a horizontal surface perpendicular to the direction of gravity to an arbitrary inclination angle at which said bottom surface forms a vertical surface parallel to the direction of gravity, and supporting said rotary body at said arbitrary inclination angles; and also while the centrifugal forces are applied to said particulates, vapor depositing said adhering material onto said particulates.
