In recent years, the development of high-performance fabric composites has attracted widespread interest, but the frictional heat accumulation of fabric composites under high-speed has resulted in frictional failure, which has hindered the application of fabric composites. To remedy this deficiency, inspired by multilayer structure of fish scales, biomimetic MXene derivative DOPO-HQ-IPTS@Ti3C2Tx was manufactured in situ, which boosted interfacial compatibility with MXene and provided remarkable enhancement in terms of mechanical perfor-mances and tribological properties of fabric composites. The tensile strength of reinforced fabric composites is enlarged by 45%. In addition, the wear rate of the reinforced fabric composites is reduced by 77%. Hence, the biomimetic nanomaterial DOPO-HQ-IPTS@Ti3C2Tx offers a simple and dependable method for obtaining fabric composites with superior overall properties.
