Comparative Stress Tolerance Of MWCNT Composites Versus Beryllium And Hastelloy Alloys In Aerospace Structures

The increasing demand for high-performance materials in aerospace structures has led to significant interest in multi-walled carbon nanotube (MWCNT) composites due to their exceptional mechanical properties. This paper presents a comparative study on the stress tolerance of MWCNT composites versus conventional aerospace alloys such as Beryllium and Hastelloy. The study explores the advantages of MWCNT composites in terms of strength-to-weight ratio, durability, and thermal stability, as well as the limitations and challenges associated with their integration into aerospace structures. Beryllium, known for its lightweight and stiffness, and Hastelloy, renowned for its high resistance to extreme environments, are examined alongside MWCNT composites under similar stress conditions. A comprehensive literature review is followed by an experimental analysis that evaluates the performance of each material in high-stress environments typical of aerospace applications. The methodology involves stress tolerance testing using standardized mechanical testing protocols for both MWCNT composites and the alloys. Results show that while Beryllium and Hastelloy provide excellent resistance to mechanical and thermal stress, MWCNT composites outperform them in specific areas, particularly in terms of weight reduction and resilience under cyclic loading. The study concludes with a discussion on the potential of MWCNT composites as a viable alternative to traditional aerospace alloys, focusing on their possible future applications and the remaining technical barriers to their widespread use in aerospace engineering.
