Fiber draw synthesis

Fiber draw synthesis

The synthesis of a high-melting temperature semiconductor in a low-temperature fiber drawing process is demonstrated, substantially expanding the set of materials that can be incorporated into fibers. Reagents in the solid state are arranged in proximate domains within a fiber preform. The preform is fluidized at elevated temperatures and drawn into fiber, reducing the lateral dimensions and br...

Design and Control of Capstan-pulley Draw System for Optical Fiber Manufacturing

Optical fiber for data communication is manufactured by the draw process, which involves heating and pulling high purity glass cylinders to diameters of 125 μm. The diameter of the glass fiber and its light-guide core must remain constant to create a product capable of transmitting high-bandwidth optical data. The draw capstan design has a significant impact on the optical fiber quality. As the...

Chromosoma (review) Kinetochore fiber formation in animal somatic cells: dueling mechanisms come to a draw

Structure Development during the Heat-Draw Process of Nylon 66 Fiber by Synchrotron X-ray Diffraction

On-line studies of structural development during continuous drawing of nylon 66 fiber at different temperatures were carried out using synchrotron wide-angle X-ray diffraction (WAXD). A unique image analysis method was introduced to analyze the two-dimensional (2D) WAXD patterns. The quantitative fractions of crystal, mesomorphic and amorphous phases were obtained. In this study, the Brill tran...

Validation Study of Draw Furnace and Helium Cooling Tube used in Optical Fiber Drawing Tower

This paper highlights the importance of validating Computational Fluid Dynamics (CFD) results from a configuration as close as possible to the subject of our research and application. The validation allows us to optimize the choice of various CFD modeling parameters such as gas flow, grid resolution and solution methodology. The validation is based on comparison between our simulated results an...
