12" wide x 36" Unidirectional (12k, 4.1oz) Twill Weave Airtight Seal - Heavy dutyWith unidirectional fabric there are no gaps between fibers and those fibers lay flat. There is no cross section weave that divides the fiber strength in half with another direction. This allows for a concentrated density of fibers that provide maximum longitudinal tensile potential. This directional strength property makes it an isotropic material, similar to wood. Unidirectional fabrics are not appropriate for parts that require a great anisotropic
