Summary

Ceramic fiber materials such as HI-NICALON (SiC), NICALON (SiC), Nextel (Al2O3-SiO2-B2O3), and others are playing an increasingly important role in the development of ceramic matrix composite materials.

The metallographic sample preparation of ceramic fiber materials has been studied. The sample preparation includes the encapsulation, grinding and polishing of these materials. The interaction and influence of various abrasives and polishing surfaces is shown using semi-automated polishing equipment.

Image Analysis was used to evaluate and characterize the ceramic composite materials automatically. Feature type analyses of the fibers were performed such as aspect ratio, sphericity and circular diameter measurements. The capabilities of image analysis are illustrated on three fiber materials.
