An isotropic epoxy resin (E=2GPa, ν=0.3) is reinforced by unidirectional glass fibers (Eglass=70GPa), aligned in the 2 direction, such that the fiber composite is transversely isotropic, with the 1-3 plane being the plane of isotropy. The elastic constants of the fiber composite are:
E1=3.3GPa,
ν13=0.25
E2=29.2GPa,
ν12=0.3
E3=3.3GPa,
G12=1.27GPa
What is the volume fraction of fibers in the composite?

PS. So I'm curious too about the source, as I can see that the question is posted in 2014, and is the same as another question in here posted this year.
