Spread tow fabric Spread Tow Fabric is often produced with carbon fiber and is widely used in the composites industry in a number of applications. Spread tow reinforcements (str) are reinforcements made using spread tow material, fabric or UD tapes, which is new category of composite reinforcements. Spread tow fabric Spread tow fabric (stf) is a type of lightweight fabric. Its production involves the steps of spreading a tow in thin and flat uni-directional tape (Spread Tow Tape, STT), and weaving the tapes to a woven Spread Tow Fabric. This technique increases the mechanical properties of the material and is also used to
