| Abstract Scope |
Most engineering applications involve cyclic loading, which is the root cause of the majority of mechanical failures. The components can experience fa-tigue due to cyclic stress, resulting in catastrophic failure at stress levels low-er than the strength values associated with static loading. 3D printing tech-nology, especially fused filament fabrication (FFF) for rapid prototyping and manufacturing, can create components with intricate geometries based on computer designs. FFF provides numerous benefits in composite fabrication, such as high precision, cost-effectiveness, and customized geometries. Me-chanical characterization of FFF parts is primarily conducted through static tests. However, many applications subject these parts to dynamic loading. In this study, fatigue tests were performed to determine the expected lifetime of polyetheretherketone (PEEK) and polyetherimide (PEI) blend and boron ni-tride (BN) incorporated PEEK/PEI blend composites. The results indicate that the blend and composite fabrication process significantly impacts the life-time of 3D printed specimens. With the addition of BN and through blend-ing, the fatigue strength of pure PEI increased by a factor of three. The in-corporation of BN was found to enhance the thermal stability and mechani-cal properties of the PEEK/PEI blend. Additionally, the fabrication of blend composites resulted in increased complex viscosity and storage modulus compared to the neat polymers. This improvement can be attributed to the good dispersion of BN in the matrix. This study offers a thorough investiga-tion of the fatigue properties of 3D-printed high-performance polymers PEEK and PEI, as well as BN-incorporated composites. |
