FiberSIM Producibility and Flattening

size: 12pt; color: rgb(0, 0, 0);">In composites design with FiberSIM, a draping simulation is used to generate fiber
size: 12pt;">paths, identify areas of wrinkling and bridging, develop flat patterns, and allow the
size: 12pt;">prediction of accurate local laminate mechanical properties such as stiffness,
size: 12pt;">permeability, volume fraction, and thickness. The simulation guides the lay-up process,
size: 12pt;">ensures repeatability and minimizes material waste. In woven fabrics, drapability is
size: 12pt;">facilitated by the fabric ability to undergo large in-plane shear deformations due to a
size: 12pt;">trellising action of warp and weft yarns. In unidirectional fabrics, fibers slide relative to
size: 12pt;">one another for in-plane shear to occur, and it is generally assumed that the distance
size: 12pt;">between the fibers remains constant whereas the fibers of the woven fabric come closer to
size: 12pt;">each other under shearing.
