How to select the dimensions for designign a hydrodynamic fiber alignment machine? 


Best insight from top research papers

To design a hydrodynamic fiber alignment machine, dimensions must be carefully selected. The dimensions of grooves in a substrate structure can be crucial. Additionally, the use of converging streamlines in fluid dynamics can aid in aligning fibers parallel to the main fluid stream. Furthermore, the tension on the fiber, controlled by brake means and idler rolls, is essential for consistent winding of fiber optic filaments. In the case of UHPC elements, the alignment of steel fibers is impacted by the flow properties and placement methods, emphasizing the need for quality control methods to assess fiber distribution and alignment. Lastly, a fiber alignment apparatus with a movable nickel leaf spring and fixed pocket can capture and lock arrays of single-mode fibers into position.

How does the fiber alignment in a cellulose nanofibril film can effect the mechanical properties of that film?5 answersThe alignment of fibers in a cellulose nanofibril (CNF) film has a significant impact on its mechanical properties. The alignment can be achieved through control of printing and drying processes, which affects the orientation of the CNFs in the film. The alignment of CNFs can be characterized globally through polarized light microscopy, which shows that drying fronts during the manufacturing process can influence the alignment. Local alignment at the surface of the film can be imaged and quantified using atomic force microscopy (AFM).
