【Abstract】 The continuous glass fiber reinforced thermoplastic composite pipe( CGF-RTP) is a new reinforced thermoplastic pipe. In this paper, the mechanical properties of the composite pipe were analyzed and studied. According to the structural characteristics of CGF-RTP, the basic theoretical assumptions of the pipeline were proposed, and the performance parameters of the pipeline materials were obtained. The finite element analysis software ANSYS was used to simulate and analyze the stress state of CGF-RTP under a certain internal pressure load. The stress analysis of CGF-RTP under internal pressure load was carried out, and the stress state between layers was studied. A reasonable failure criterion was proposed and the mechanical model of CGF-RTP was given.更多还原
