Design and Evaluation of Operando Magneto-Assisted Direct Writing Processing and Effects of Fiber Alignment in Printed Composite

Abstract

The use of Direct Writing (DW) and Additive Manufacturing (AM) technology has expanded a realm of complex tools and polymers in manufacturing extrusion-based composites. Incorporating an external magnetic field and specialized curing process widens the extent of controlling a functional microstructure by specification of the fiber alignment. The dominant shear flow directs the fibers, in this case nickel nanowires, to align in the flow direction for this particular method. This work is focused on development of a printhead customized for these methods to create desired fiber orientation by overcoming shear force and fixating fibers in the desired orientation through curing. This printhead will reduce lead time and evaluates the printed composite to observe the increased strength of the mechanical and electrical properties of the composite due to the fiber alignment. The final printhead will be a summation of this process that consolidates these processes of extrusion, curing, and printing modified to the parameters of the nickel nanowire microstructure.
