Optical and mechanical properties of fiber-reinforced ceramic matrix optically transparent composites

The idea of increasing the fracture resistance of optically transparent Ceramics by incorporation of continuous fibers with a small expense in their light transmission was applied to a SiC (SCS-6) fiber-reinforced magnesium aluminate spinel matrix composite. It was found that although there is a slight decrease in the light transmittance of the transparent monolithic matrix with increasing fiber volume fraction, a fail-safe mechanism appeared in the composite by the bridging effect of the intact fibers
