- Abstract
A novel additive manufacturing technology is used to create micro-composites, which can be tailored for specific end-use applications. The Field-Aided Laminar Composite (FALCom) process uses specifically focused electric fields to align nano- to micro-sized particles into chain-like structures, which are referred to as pseudo-fibers. These pseudo-fibers are then immediately frozen into place by incident ultraviolet radiation on the photopolymer matrix. The pseudo-fibers are arranged by design, and they are used to create three-dimensional composite structures. Multiple filler materials have been evaluated for use in the FALCom system; however, this report describes aluminum micro-particles that are aligned and oriented in an acrylic photopolymer matrix. A description of the technology and a review of experimental processing are shown, and conclusions, as well as, future work are discussed.
