= 4. You need to design a CFRP composite with a 1-direction stiffness of E₁ 180 GPa using the above materials from Problem 3. You are told to use a 0/90 layup in making this composite and that the volume fraction of the fibers after curing is Vf = 62%. a. What are the relative thicknesses of the 0° and 90° layers? Note: the 0° layer is oriented in the 1 direction. (10 points) b. What is the transverse stiffness (E2) of the composite with the above thicknesses? (5 points) Hint: this is technically a laminate question, but you can use a rule of mixtures to solve it. = 4.
