15. Determine the transverse modulus of a unidirectional carbon/epoxy composite with the properties E2f = 14.8GPa, Em = 3.45GPa, Vm = 0.36, V = 0.65. 16. The fiber and matrix properties and in-plane properties of AS4/3501-6 car- bon/epoxy laminate (60 vol% carbon) are given in the table below. Use the law of mixture to calculate the in-plane laminate properties E1, V12, G12, 1, and p. Compare and discuss results with those in table.
