摘要： Unwinding systems and methods are provided for unwinding a fiber from a bobbin. The unwinding system can include an axle defining a first axis extending an axial direction, a bobbin rotatably mounted around the axle, a pulley positioned to receive the fiber from the bobbin, wherein the pulley is rotatable around a second axis, and a sensor positioned between the bobbin and the pulley. The bobbin is moveable along the axial direction, and wherein the fiber extends tangentially from a surface of the bobbin.

摘要： Methods for coating a fiber are provided. The method can include unwinding a silicon carbide-containing fibrous material from a bobbin rotatably mounted around an axle and forming a boron nitride coating onto the silicon carbide-containing fibrous material. The bobbin is moved along the axial direction such that the silicon carbide-containing fibrous material defines an unwind angle with the axial direction, with the unwind angle being maintained between about 80° to about 100°.
