| Abstract Scope |
Here we demonstrate a stereolithography-inspired additive manufacturing method to fabricate high strength and stiffness continuous carbon fiber reinforced composites. Woven carbon fiber fabric was laser-cut to desired geometries resulting in high-resolution composite fabrication. An aerospace grade dual-curable photopolymer resin was used as a high-performance matrix material and was impregnated into carbon fiber fabric with a heated resin bath. Following impregnation, compression-consolidation with a FEP lined glass plate and custom fixture minimized porosity and enabled control over the resultant fiber volume fraction. UV-curing of the photopolymer-infused composite enabled multi-layer printing in a semi-cured state, while thermal post-curing was utilized to reach the final properties. This process resulted in fabricated composites with high tensile and flexural properties for unidirectional and woven composites. Microstructural characterization revealed the benefits resin-infusion and consolidation by minimizing void formation. Due to the use of a glass consolidation plate, this process resulted in 3D printed woven composites with an excellent surface finish with very low surface roughness. |
