 This research work investigates the impact of different surface treatments on Cysil fibers and their epoxy composites, revealing improved structural, thermal, and tribological properties, as well as enhanced wear resistance in chemically treated SFIEC compared to untreated SFIEC. The most significant factors affecting wear volume loss were found to be applied load and sliding distance. This article was authored by Sudoka Bahara, Rakesh Kumar Gautam, Sunil Mohan, and others.
