Patent Images
1. A fiber-reinforced system having mechanical wear erosion resistance, said fiber-reinforced system comprising:
- a first structural fiber-reinforced ceramic matrix composite part having a wearing surface;
a second structural fiber-reinforced ceramic matrix composite part having a wearing surface in sliding contact and mating with said wearing surface of said first structural fiber-reinforced ceramic matrix composite part; and
mechanical wear erosion-resistant layers, each disposed on said respective wearing surfaces of said first and second parts, wherein said mechanical wear erosion-resistant layers resist mechanical wear erosion of said wearing surfaces due to the sliding contact.

Abstract
Structural ceramic matrix composite material to be employed as automotive engine parts and the like is provided with erosion-resistant qualities in several ways. For one, an erosion-resistant material is applied to the surface as by plasma spraying. The erosion-resistant material can also be mixed with the fibers of the material, particularly near the surface.
