Abstract: Flexible composite pipes, as alternatives to traditional metal pipes, have attracted much attention in the fields of deep-sea oil and gas development and hydrogen energy transportation due to their advantages such as lightweight, corrosion resistance and high flexibility. This paper focuses on the material, structure and function of flexible composite pipes from a multi-dimensional cross perspective, and deeply analyzes the synergy mechanism among the three, aiming to provide a systematic reference for scientific research and practice in related fields. By sorting out the research trends of flexible composite pipes at home and abroad in recent years, this paper elaborates on the research progress from the classification system to the actual engineering application of flexible composite pipes, and at the same time makes prospects for the challenges and development directions it faces, in order to assist the continuous optimization and upgrading of infrastructure construction in the energy, chemical and other industries.

Key words: flexible composite pipes, reinforced thermoplastic pipes, classification system, composite materials
