“…The draping simulation developed by Meng (2012) The inputs for the fabric initial conditions are: tow width, fabric thickness, shear locking limit, and number of tows. Using these parameters, the simulation generates a lay-up using the naïve lay-up method (Figure 10(left)) and another, deterministically optimized shear angle distribution lay-up using a pre-sheared fabric (Figure 10(right)).…”

“…A mold was created to test the fabric samples' ability to conform to a 3D geometry with significant curvature. The mold was designed with the help of draping simulation software (Meng 2012). The goal of the mold design was to create a doubly curved shape severe enough that it would force normal fabric to exceed its shear locking limit and thus create out-of-plane deformations.…”
