Research Abstract

The purpose of this study is to develop a screening system of ceramics for space and aeronautics based on theory of Non-destructive Inspection presented by Matsuo et al..
First, we examined the strength, fracture mechanical properties, damage process under uni-axial compression, and thermal shock resistance for isotropic graphite and alumina/graphite.
Using these experimental results, we established a new theory of non-destructive inspection based on fracture statistics presented by us. Then, we determined the screening region and screening threshold crack size. We carried out a simulation for non-destructive evaluation, and examined the validity of the new theory by comparing the ratio of the number of survived specimen vs. rejected ones. We concluded that our theory is valid for ceramics.
As stated in the above, in this study, we developed a new theory of inspection for ceramics. This theory is very powerful and is even applicable to ensure the strength reliability of ceramics and ceramic matrix composite the surface or inner part of which were strengthened by some method, for instance, infiltration by CVD.
