| Abstract | ||
| The non-destructive assessment of thermo-mechanical characteristics of exceptionally rigid structures composed of natural composite fibers, facilitated by high-force dynamic mechanical investigation, has unveiled new insights previously unattainable with conventional static and impact test methods. This groundbreaking study delves into the potential of natural fiber composite sandwich panels, featuring both aluminum and aramid honeycomb cores, designed for advanced multi-passenger airplane structures. By comparing various panel cores, the study evaluates equal stiffness and damping capabilities across critical flight frequencies ranging from 1 to 100 Hz. Remarkably, the research reveals that the fatigue behavior of these natural fiber sandwich panels is intricately dependent on both the core material and the applied static load. Furthermore, temperature sweeps conducted during the study provide an innovative approach to detecting variations in the post-processing of natural fiber laminated panels. These temperature sweeps also highlight changes in the transition temperature of the matrix material, offering deeper insights into the material's performance under different thermal conditions. The findings of this study underscore the crucial role of core material selection and processing conditions in enhancing the performance of natural fiber composites for aerospace applications. By leveraging dynamic mechanical analysis, researchers can gain a more holistic understanding of material behavior under realistic operational conditions, paving the way for the design and maintenance of lightweight, durable, and efficient aircraft structures. This research not only advances the field of natural fiber composites but also holds significant implications for the future of sustainable and high-performance materials in the aerospace industry. | ||
