Novel macrocomposite bodies and methods for making the same

摘要

This invention relates to novel macrocomposite bodies. More particularly, it has been discovered that the properties of a ceramic, ceramic matrix composite or metal matrix composite body may be improved by providing on at least a portion of the surface of the body a polymer-based material which serves to protect the body from damage which might occur in the absence of the polymer-based material. One particularly preferred embodiment of the present invention is a macrocomposite shaft sleeve. Another particularly preferred embodiment is a macrocomposite apex used in a hyrocyclone separator.
