Introduction
Aramid fiber is renowned for its exceptional heat resistance, which allows it to maintain stable performance in many extreme environments. Whether in aerospace, firefighting, or petrochemical industries, the high-temperature tolerance of aramid fiber lays the foundation for its applications. This article delves into the heat resistance of aramid fiber and the scientific principles behind it.
Mechanism of Heat Resistance in Aramid Fiber
The heat resistance of aramid fiber primarily stems from its unique molecular structure. The aramid molecular chain contains a large number of benzene ring structures, which endow aramid fiber with high rigidity and thermal stability. Even at temperatures as high as 370°C, aramid fiber can still maintain its excellent performance. Its heat-resistant characteristics make it an ideal choice for some extreme high-temperature application fields.
