Abstract Scope |
The recent manufacturability of fiber-reinforced composites using robotic platforms has facilitated the realization of components with highly engineered layup schedules and fiber orientations. However, the process-property nexus at the foundation of this new class of materials calls for extensive characterization of the physical and mechanical properties. Therefore, this research aims to elucidate the process-property interrelationships of additively manufactured, continuous fiber-reinforced polymer matrix composites, additively manufactured using an advanced robotic printing system as a function of the processing parameters. This platform was used to fabricate several generations of composite panels with various layup schedules and fiber types. The dimensional accuracy was evaluated by comparing the target and printed geometries. Samples extracted for each panel were submitted to flexural testing at a quasi-static loading rate. Flexural testing was augmented by full-field strain measurements using digital image correlation (DIC) to resolve the kinematics of deformation as a function of printing configurations. Mechanical measurements were coupled with micrographic analyses using scanning electron and optical microscopies to ascertain the failure mechanisms. The outcomes of this research help define the design envelope of this novel class of material. |
