Title: **Innovative Contributions of Heshmat Aglan in Polymer and Rail Repair Technology**
Introduction
Heshmat Aglan, an accomplished inventor located in Tuskegee, Alabama, has made significant advancements in the fields of polymer technology and railway maintenance. With a total of three patents to his name, Aglan's work showcases his dedication to innovation and improving material performance, particularly through nanotechnology and welding techniques.
Latest Patents
Aglan's latest patents include the development of nanostructured thermoplastic polyimide films. These structured films, which incorporate multi-walled carbon nanotubes (MWCNTs), exhibit enhanced mechanical performance characteristics. Specifically, the strength of the new polyimide films, dried at 60°C, has increased by 55% and 72% for 0.1 wt % and 0.5 wt % MWCNT loadings, respectively. Notably, the fracture resistance also improves with the addition of 0.1 wt % MWCNTs, although it diminishes with higher loadings. Aglan has successfully managed the annealing temperatures to ensure optimal strength as MWCNT levels increase.
Another key patent involves a multi-pass gas metal arc welding (GMAW) technique designed for the in-situ repair of railway railhead defects. In this innovative approach, Aglan details a method where the defect is addressed by machining a perpendicular slot in the railhead, while preserving the integrity of the web and base. The process utilizes a sufficient number of GMAW passes to fill the void, made from a weld material compatible with the specific steel type. For pearlitic steel rails, he introduces post-weld heat treatments to enhance the structural integrity of the weld.
