Thesis Overview

The project titled "Development of High-Performance Lightweight Metal Matrix Composites for Aerospace Applications" aims to address the growing demand for advanced materials in the aerospace industry. This research focuses on the development of metal matrix composites (MMCs) to enhance the performance and efficiency of aerospace components, particularly in terms of weight reduction and mechanical properties. The aerospace industry requires materials that are lightweight yet strong, durable, and corrosion-resistant to ensure the safety and reliability of aircraft structures and components. Traditional materials like aluminum and titanium alloys have limitations in meeting the increasing performance requirements of modern aircraft. Metal matrix composites offer a promising solution by combining the lightweight properties of metals with the superior strength and stiffness of reinforcement materials such as carbon fibers, silicon carbide, or alumina. The research will involve the design, fabrication, and characterization of lightweight metal matrix composites with tailored properties suitable for aerospace applications. Various manufacturing techniques, such as powder metallurgy, casting, and additive manufacturing, will be explored to produce MMCs with optimized microstructures and mechanical properties. The focus will be on enhancing the specific strength and stiffness of the composites while maintaining good fatigue resistance and thermal stability. The project will also investigate the effects of different reinforcement materials, volume fractions, and processing parameters on the performance of MMCs. Advanced characterization techniques including scanning electron microscopy (SEM), X-ray diffraction (XRD), and mechanical testing will be employed to analyze the microstructure and mechanical behavior of the developed composites. By developing high-performance lightweight metal matrix composites, this research aims to contribute to the advancement of materials technology in the aerospace industry. The outcomes of this study are expected to lead to the fabrication of novel MMCs that can be used in critical aerospace components such as engine parts, structural elements, and landing gear, enabling improved fuel efficiency, reduced emissions, and enhanced overall performance of aircraft. Overall, this research project on the development of metal matrix composites for aerospace applications holds significant potential to revolutionize the materials used in aircraft manufacturing, ushering in a new era of lightweight, high-performance materials that meet the stringent requirements of the aerospace sector.
