Durability and Resilence of Hyperloop Infrastructure
Abstract: ABSTRACT: The Hyperloop is a revolutionary concept for high-speed ground transportation that involves passenger pods traveling through low-pressure tubes at near-supersonic speeds. Originally proposed by SpaceX in 2013, the concept aims to offer a cost-effective and faster alternative to conventional rail systems and short-haul air travel. This study addresses a critical component of the Hyperloop's success—structural durability. Key concerns include material fatigue due to repetitive high-speed movement, pressure fluctuations within …

Self-healing Polymer Nanocomposites study using filler effect
Abstract: Polymers, while versatile, often lack the desired mechanical strength, thermal stability, or barrier properties for high-performance applications. This limitation is elegantly addressed by creating polymer nanocomposites. These materials are formed by incorporating small amounts (typically 1-5 wt%) of nanoscale fillers (e.g., carbon nanotubes, graphene, silica, clay, metal oxide nanoparticles) into a polymer matrix. The magic of nanocomposites lies in the incredibly high surface area-to-volume ratio of the nanoparticles and their …
