Abstract Scope |
Additive manufacturing (AM) is a useful tool yet to be rigorously applied to the manufacturing of energetic materials. A material with high viscosity and yield stress is required for the AM of energetics. The goal of the project is to develop an energetic initiator ink with easily customizable parameters such as composition and print speed. This project focuses on characterizing the viscosity of an energetic initiator ink using a rotational viscometer. Changes to the particle size ratios, binder system, and catalyst concentration will be done to optimize printability for given applications. The data indicates that viscosity is dramatically changed with particle size ratios. Additionally, catalyst concentration is shown to significantly impact the cure rate in a linear fashion. Machine learning models to accelerate compositional changes and optimization will be created upon the generation of sufficient training data. These models will be used to rapidly and accurately customize ink parameters. |
