Comparative Stress Tolerance of MWCNT Composites Versus Beryllium and Hastelloy Alloys in Aerospace Structures

This paper presents a comparative study of multi-walled carbon nanotube (MWCNT) composites and conventional aerospace alloys, specifically Beryllium and Hastelloy, focusing on stress tolerance. MWCNT composites are examined for their superior strength-to-weight ratio, durability, and thermal stability compared to Beryllium, known for its lightweight and stiffness, and Hastelloy, recognized for its resistance to extreme environments. The study includes a literature review and experimental analysis using standardized mechanical testing protocols. Results indicate that while Beryllium and Hastelloy excel in mechanical and thermal stress resistance, MWCNT composites demonstrate advantages in weight reduction and resilience under cyclic loading.
