摘要
连续玻璃纤维增强热塑性复合管(CGF-RTP)是一种全新的增强热塑性塑料管。本文对该复合管的力学性能进行了分析与研究。根据CGF-RTP的结构特征,提出了该管道的基本理论假设,同时得出管道相关材料的性能参数;运用有限元分析软件ANSYS,模拟分析了CGF-RTP在一定的内压载荷下的受力状态;对CGF-RTP在内压载荷下进行应力分析,研究了各层之间的应力状态;提出了合理的失效准则,给出了CGF-RTP设计的力学依据。
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.
