Summary

The effect of specimen size on the tensile properties of woven fabric Al2O3 fiber - Al2O3 matrix composites was investigated. Two types of specimen with different thickness were studied, namely, 5-ply and 10-ply composites with varying gage length. X-ray radiography, optical microscope and scanning electron microscope were used to examine damages in specimens. It was found that the strength of the composite was independent of gage length. However, the effect of thickness (number of ply) on strength was observed, that is, the strength decreased with increasing thickness.
