Question 20
XE-CNAT2 marksNeeds review
Silicon carbide (SiC) particles are added to Aluminum (Al) matrix to fabricate particle reinforced Al-SiC composite. The resulting composite is required to possess specific modulus (E/ρ; E: elastic modulus, ρ: density) three times that of pure Al. Assuming iso-strain condition, the volume fraction of SiC particles in the composite will be ______ (round-off to two decimal places).
Material | E (GPa) | ρ (g.cm⁻³) |
|---|---|---|
Al | 69 | 2.70 |
SiC | 379 | 2.36 |
