In one direction (usually in a direction, there is also a parallel unidirectional fabric) with a large amount of textile yarn or non-woven yarn, in the other direction there is only a small amount and usually fine yarn, the result is actually the full strength of the cloth in one direction of a fabric.
The English name of the one-way fabric is Uni-Directional Fabric or Cloth, sometimes referred to as UD fabric, UD cloth, a textile material/fabric that is woven by special equipment and treated after treatment. The fabric weaving method by a variety of, common for woven unidirectional fabrics, is made with German Dornier weaving, generally for radial unidirectional fabrics, mainly used for building bridges for seismic repair and reinforcement reinforcement, such as Japan's Toray's carbon fiber one-way fabric and the United States Hershey carbon fiber company HEX-3R one-way carbon fiber fabric Non-latitude carbon fiber fabric, i.e. generally believed to be UD cloth, is actually a pre-immersion sheet, is a special equipment to arrange the fibers in one direction neatly and resin bonded together, composite a thin film or off-form paper or even fiber mesh;
Fabrics sewn from polyester yarnares are mainly used in the aerospace and marine industries. Common lying glass fiber E-Glass, high-strength fiber glass S-Glass and a variety of bulletproof yarn fiber (carbon fiber CARBON, aramid 1414, Kevlar, ultra-high molecular weight polyethylene) production applications. Features are: good vibration reduction effect, small expansion coefficient, small skeleton, small deformation, and is widely used in the aviation industry, such as radar cover, electronic equipment cabin, engine casing, engine blades, hatches, straight-out aircraft pulp leaves, etc.; Ice hockey rods, etc.; for chemical industries, such as three-dimensional horizontal storage tanks, pipes, workbench, etc.; for medical industries, such as splints, bandages, artificial respirators, etc.; for military industries, such as protective armor, large-calibre artillery, tank weight wheels, etc.; other industries, such as enhanced prefabricated parts for construction, sword bars, swords and swords belts, etc.
