    | Abstract Scope | This project investigates a novel additive manufacturing (AM) technique, reactive extrusion AM, for carbon fiber reinforced thermosetting resins. The process utilizes highly exothermic resin/catalyst systems with fast curing cycles, eliminating the need for an external energy source. Chemical cross-linking occurs between the printed layers, resulting in parts with strong interlayer properties. Carbon fibers are added to the thermosetting resin for mechanical reinforcement with fumed silica as a rheology modifier. Inter- and intra-layer tensile properties of REAM neat polymer and composites reinforced with 20wt.% of milled fibers are measured. These properties are correlated, using a mechanics model, to the fiber length/orientation distributions data attained from X-ray-micro computed tomography(uCT). Degree of curing is also characterized using Differential Scanning calorimetry (DSC)and correlated to thermal images captured during parts’ AM. |
