In the aerospace sector, material selection is a crucial element in the development of components and structures that meet strict technical and regulatory requirements. The use of advanced materials is essential for improving performance, reducing weight, and ensuring the safety of aviation applications. However, the introduction of new materials involves a complex validation process, which includes a wide range of experimental tests and necessary interaction with the Authorities (EASA-European Union Aviation Safety Agency and FAA-Federal Aviation Administration) to obtain flight safety certification. The adoption of a composite material requires a detailed and costly process in terms of time and resources. This process is divided into several phases: • Preliminary go/no-go tests, which consist of initial checks to determine the material’s feasibility against the minimum required standards; • General characterization, which involves a thorough analysis of the material’s mechanical, thermal, and chemical properties; • Application evaluation and certification, which involves carrying out specific tests required by the Authorities for the intended applications, ensuring regulatory compliance.
