Question
03: A composite material product consists of an aluminum metal matrix
reinforced by a 15% volume fraction of graphite fiber. Use the given
properties of aluminum and graphite to determine:
1. The density of the composite.
2. The Mass fractions of the aluminum and graphite
3. The transverse Young's modulus of the aluminum/ graphite composite.
4. The axial Young's modulus of the aluminum/ graphite composite.
5. Compare the results of the transverse and axial Young's modulus of
the pure aluminum alloy with the results of the transverse and axial
Young's modulus of the composite found in 3 and 4 and give the
improvement or reduction percentages.
Given: Aluminum pm = 0.0027 g / mm', E m = E2m = 70 GPa
Graphite p= 0.0018 g / mm’, E1f =220 GPa, E = 20 GPa
