[0003] Offshore oilfield platforms are complex and high-risk working environments. Fire safety is particularly critical, and the development and application of new materials and new processes are essential to improving fire safety. Carbon fiber composite materials have gradually become one of the key materials for offshore oilfield fire pipeline systems due to their excellent performance.
