| Abstract Scope |
Fiber-reinforced thermoset composites (FRTCs), widely used in diverse industries, require timeand energy-consuming processing, which is unsuitable for customizable agile manufacturing. Weaddress the demand for rapidly curable FRTCs by implementing the frontal polymerization (FP),a self-propagating exothermic reaction process, on the direct ink writing (DIW) platform. Usingphysics-based modeling and chemical synthesis techniques, we determine the effect of fibermicrostructure and chemical composition on the curing of radical-induced cationic frontalpolymerization (RICFP) process. We show the dual initiator mechanism (UV and/or heat) forRICFP to control the curing conditions for multilayered composites. The results are used todevelop a transient thermochemical computational model in a finite element framework tosimulate heat generation and front propagation. The insight gained into the impact of the compositecompositions on the thermo-mechanical properties will guide us in designing the extrusion andcuring conditions for the DIW printing of FRTCs with disparate properties. |
