Additive Manufacturing System for Advanced Continuous Fiber Composite Structures
Abstract
The objective of this proposal is to use the CF3D composite additive manufacturing system to explore new materials, processes, and designs for complex aerospace structures. This includes the partial purchase of a CF3D Enterprise printing system and the development of off-printer test bed which can probe fundamental processing-structure-properties relationships and explore variations in processing methods using printer relevant hardware. The proposed equipment will allow us to make four significant advances to composite printing- (1) Fabricating thermal and UV-activated frontally polymerized additive composites; (2) Expand the currently limited resins options (2) for CF3D to high viscosity resins and nanocomposites; (3) Develop the capability to print with multiple resins in a modulated or sequential manner to enable structured filaments; (4) Use the sequential resin impregnation to improve longitudinal strength of printed composites by reducing the fiber-to-fiber contact within the deposited tow.
