Abstract Scope |
This study investigates the influence of thermal history on the mechanical properties of fused filament fabrication samples, specifically the fracture toughness and subsequent fatigue life performance. The thermal history of nylon and carbon fiber filled nylon is manipulated through nozzle temperature. Compact tension samples are fabricated and subjected to both static and fatigue loading to assess fracture toughness of the modified samples under different loading conditions. Thermal history analysis is conducted using thermography to determine the diffusion history of the samples. The experimental design allows for the systematic evaluation of how varying levels of nozzle temperature, and consequently different thermal histories, influence the resultant fatigue resistance and fatigue life. These findings contribute to advancing the broader application of additive manufacturing by enabling the production of components with reliable performance for functional applications. |
