A \([90 / 0 / 90]_{\mathrm{s}}\) laminate is fabricated from laminae consisting of isotropic fibers \(\left(E_{\mathrm{f}}=220 \mathrm{GPa}, v_{\mathrm{f}}=0.25\right)\) embedded in an isotropic matrix \(\left(E_{\mathrm{m}}=3.6 \mathrm{GPa}\right.\), \(\left.v_{\mathrm{m}}=0.4\right)\). Each lamina is \(0.25 \mathrm{~mm}\) thick, and the \(0.01-\mathrm{mm}\)-diameter fibers have been precoated with a \(0.00125-\mathrm{mm}\)-thick sizing, which is the same as the matrix material. The precoated fibers are arranged in the closest possible packing array in the matrix. Using both micromechanics and laminate analysis, find the laminate engineering constants \(E_{x}, E_{y}, G_{x y}\) and \(v_{x y}\). The laminate \(x\)-axis is parallel to the \(0^{\circ}\) lamina orientation.
