Question

Problem 3: (30 points) The modulus of a [Om 90n] laminate (m number of 0° fiber layers followed by n number of90 be approximated using the following "averaging" equation berlayers 1 m+n xm+ Suppose a [o/90/0)3s laminate is constructed using continuous T-300 fibers in an epoxy matrix. Calculate modulus of the laminate using the averaging equation, and compare it to its value calculated by the laminati theory. Use the material properties of the unidirectional lamina as: Ei = 133.44 GPa , E,-8.78 GPa , v,2 = 0.26 , G12-3254 GPa
