Homework Equations


Halpin Tsai equation:[/B]
upload_2018-9-17_2-44-55.png

Voigt model:
P*=VfPf+VmPm

Vf= volume of fiber/ volume of composite
Vm= volume of matrix / volume of composite
ζ= estimated parameter
Pf, Pm= fiber and matrix properties
V_v=1-Vf-Vm

The Attempt at a Solution


Since there is no V_v in the Halpin Tsai's equation, I am confused on how the Voigt Model obtained Vm from Halpin Tsai's equation

There is no V_v in the Voigt model either. Maybe you are supposed to assume that the volume of voids is zero?
