Some pretty good info in that last post. A couple things I would like to add. The practice of running fiber orientation is a good one however you need to know what your reference point is. The fiber orientation on a plain weave fabric runs in two directions the " Warp " fiber runs the length of the roll and the " fill " fiber runs at 90 degrees to the roll. When fiber orientation is specified it is in relationship to the warp. When talking about unidirectional fabrics, they are usually only available in Carbon Fiber.
