0 90 laminate. Cross ply laminates are uniquely composed of laminae with fibre orientations of 0 and 90. The concept of using 0 90 laminates to evaluate lamina compressive strength exploits the transverse constraint provided by the 90 plies in combination with increased buckling stability obtained by positioning the 0 plies away from the neutral axis. The laminate is subjected to in plane loads nx 60 kn m and nxy 4 kn m. Resin is orders of magnitude less stiff than carbon fiber.

For instance laminates are constructed from a mix of plies in 0 45 45 and 90 orientations such that their in plane elastic properties are isotropic before damage. The laminates are specially orthotropic. Third under load the fibers will scissor and change orientation again only resisted by resin stiffness. Since for these orientations both q 16 q 26 0 independently of thickness and stacking sequence for these laminates a16 a26 0 i e.
