METHOD AND APPARATUS FOR COATING A COMPLEX OBJECT AND COMPOSITE COMPRISING THE COATED OBJECT

摘要

Disclosed are coating apparatus and coating methods to uniformly coat complex objects. The apparatus can comprise a first gimbal connected to a first rotational mechanism to allow rotation of the first gimbal around or about a first axis, a second gimbal connected to the first gimbal to allow rotation around or about a second axis and a third gimbal connected to the second gimbal to allow rotation around or about a third axis. A second rotational mechanism is connected to the second gimbal to rotate the second gimbal around or about the second axis and a third rotational mechanism is connected to the third gimbal to rotate the third gimbal around or about the third axis. An object holder is connected to the third gimbal. When the object holder engages a complex object which has been coated with a coating solution, the coated object is rotated around or about two or three axes to produce a multidirectional centrifugal force which together with the force of gravity creates a three dimensional tensor force. This force causes the coating solution to spread evenly over all or part of the complex surface of the object to produce a uniform thin film. Composites comprising the object with a uniform thin film coating on at least all or part of the complex surface are also disclosed.
