Polymeric nanocomposites are significant engineering materials predominantly due to their enormous potential to meet a spectrum of applications, particularly in improving the strength-stiffness properties, thermal properties, optical and electrical properties. The exploitation of polymer nanocomposites in the aerospace industry is found to be attractive in recent times, since they can provide significant strength to the components with lightweight characteristics. In addition, a wide variety of polymers can be tuned with carbon and non-carbon-based nanomaterials and deployed as archetypes in the structural components of aerospace applications. Accordingly, this chapter consider the key properties of different nanomaterials in polymers as a function of nano-scale approach. Furthermore, this chapter is also dealing with the challenges that need to surmount the technological enduring of the polymer nanocomposites for advancements in the aerospace structural applications in the coming future.

A review on the advances achieved in the last 25 years in the development of hybrid nanocomposites based on polymer matrix for aerospace applications is presented here. The chapter analyzes the state-of-the-art strategies used in the design of materials that support the different conditions of the space environment. These materials are aimed primarily at structural applications, electromagnetic interference shielding, self-sensing, and self-healing, although they are not restricted to these applications. The introduction of metallic, ceramic, carbon-based nanomaterials such as carbon nanotubes and graphene, as well as two-dimensional materials have been used with a successful impact. Despite the significant advances that have been reached, much work must be done to achieve complete reliability for all properties required to protect the systems against the hazardous conditions found in space. Therefore, futuristic visions of the actions that must be carried out are raised in this chapter.

Pin On Disk

The 4340 are classified as ultra-high strength steels used by the aviation industry and aerospace applications such as aircraft landing gear and several structural applications, usually in quenched and tempered condition. In this situation occurs reduction of toughness, which encourages the study of multiphasic and bainític structures, in order to maintain strength without loss of toughness. In this study, ferritic-pearlitic structure was compared to bainitic and martensitic structure, identified by the reagents Nital, LePera and Sodium Metabisulfite. Sliding wear tests of the type pin-on-disk were realized and the results related to the microstructure of these materials and also to their hardnesses. It is noted that these different microstructures had very similar behavior, concluding that all three tested pairs can be used according to the request level.

Abstract The metallurgical aspects of turbomachinery components, both during manufacture and service intervals, are of particular interest because they dictate performance, degradation, and probability of defect formation. As certaining the microstructural state without destructive cut-ups is difficult. Nondestructive methods such as x-ray diffraction or ultrasonic testing can provide some amount of metallurgical characterization but are limited to surface measurements or point-by-point inspections. Ultrasonic Resonance methods such as Process Compensated Resonance Testing (PCRT) can greatly supplement the inspection and qualification of Industrial Gas Turbine (IGT) blades. The resonance information collected from a component forms a resonance fingerprint, which is dependent on the material, microstructure, geometry, and the presence of defects. PCRT is an established Nondestructive Testing (NDT) method that has seen extensive use in the aerospace industry for both the detection of damage/defects and undesirable microstructural deviations. This experience from aerospace applications can be leveraged for improved metallurgical inspection methodologies in the power generation industry. Here we present and discuss several PCRT case studies from the aerospace industry as well as early PCRT experiences from power generation. Ongoing and upcoming work is also briefly discussed.
