Consider a 7 layer laminate. The 2 outer-most plies (one on top, one on bottom) are 4mm thick fiberglass. The other plies are 2mm thick graphite plies. a) What is N for this laminate? b) Draw a figure of this laminate, including layer number, material, and generic ply orientation angles to make this laminate symmetric c) Identify the middle surface and the z-direction. d) What is the value of t? t-raphine? tk-fiberglass? e) Dimension through Zx on the Figure, both symbolically and numerically, f) Write an array of Za through Zx both symbolically and numerically, g) If the middle layer had a fiber orientation angle of 25', how would you denote it in the laminate prescription using symmetric shorthand notation.
