Question

Chapter 7, Problem 7.1P

To determine

Effect on toughness of alumina matrix on embedding SiC fibers.

Expert Solution & Answer

Answer to Problem 7.1P

Toughness of the ceramic matrix composite gets enhanced/increased.

Explanation of Solution

When a material comprises of two or more other materials at a "microscopic" level/scale such that they have distinct chemically phases, the material is termed as Composite material. The "constituent materials" of a composite have different properties which results in an enhanced property for composite material.

The Silicon carbide (SiC) fibres have high values of specific strength, specific modulus and temperature resistance, corrosion resistance. Toughness of a composite is dependent on the deflection of crack at the interface.

Now,when theSiC fibers are reinforced in the alumina matrix the crack in the substrate (alumina)does not pass through the SiC whisker/fiber and it expands by bypassing the SiC whiskers,which lead crack deflection. It occurs as the SiC whisker have high strength modulus and hence more energy is required to propagate a crack through the composite. Hence, it leads to high toughness of the SiC embedded alumina composite.
